Merge branch 'bugfix/xtal_freq_after_wdt_reset' into 'master'
rtc_clk_init: handle case when XTAL frequency has already been set
On first reset, ROM code writes the estimated XTAL frequency into
RTC_APB_FREQ_REG (aka STORE5). If the application doesn’t specify exact
XTAL frequency (which is always the case for now), rtc_clk_init will
guess what kind of XTAL is used (26M or 40M), based on the estimated
frequency. Later, detected frequency is written into RTC_XTAL_FREQ_REG
(aka STORE4).
When the application switches clock source to PLL, APB frequency changes
and RTC_APB_FREQ_REG is updated. If the application encounters an RTC
WDT reset, RTC_APB_FREQ_REG will not be updated prior to reset. Once the
application starts up again, it will attempt to auto-detect XTAL
frequency based on RTC_APB_FREQ_REG, which now has value of 80000000.
This will fail, and rtc_clk_xtal_freq_estimate will fall back to the
default value of 26 MHz. Due to an incorrect XTAL frequency, PLL
initialization will also take incorrect path, and PLL will run at a
different frequency. Depending on the application this may cause just
garbage output on UART or a crash (if WiFi is used).
This change checks if RTC_XTAL_FREQ_REG has already been set before trying
to estimate XTAL frequency based on the value of RTC_APB_FREQ_REG, and
uses RTC_XTAL_FREQ_REG value if it is valid.

mbedtls port: Fix detection of EWOULDBLOCK/EAGAIN with non-blocking sockets
Since mbedtls_net_errno is reset by fcntl, it is reset after calling
net_would_block, so the call to mbedtls_net_errno in mbedtls_net_recv
and mbedtls_net_send will always get back 0. This change propagates
the value returned by mbedtls_net_errno up through net_would_block,
to allow the correct error value to be used and avoid a redundant
call to mbedtls_net_errno.

Make sure LD -L option is calculated correctly when the project Makefile has specified SRCDIRS components that are not directly below Makefile folder level.
For example,
SRCDIRS = comp_a happy/comp_b /c/dev/comp_c
Then the following are built:
build/comp_a/libcomp_a.a
build/comp_b/libcomp_b.a
build/comp_c/libcomp_c.a
But when LD is run the -L is calculated as follows
-L build/comp_a
-L build/happy/comp_b
-L build//c/dev/comp_c
This means comp_b and comp_c are not found by LD. With this change set -L is calculated correctly for comp_b and comp_c

spidriver: Display length errors correctly
SPI transfer length is bits, not bytes, so the error should indicate bits. Also, there are separate lengths for rx and
tx (confusingly named rxlength and length... if rxlength is 0, length is used). The code checks the tx length for the
rx, so it never validates rxlength.

Merge branch 'bugfix/dont_log_before_bss_inited' into 'master'
Remove ESP_EARLY_LOGI before bss is initialized; it crashes the CPU
There's an ESP_EARLY_LOGI line that can get called before the BSS is initialized; the early logging code doesn't cope well with that: it checks if FreeRTOS is up, but the variables it uses for that contains garbage because it isn't cleared yet, giving the wrong result. The logging code then tries to set a mux, crashing the entire system. This patch removes the log line and adds a warning at the BSS initialization line not to do anything complex before that point.

esp32: Adds functionality for application tracing over JTAG
- Implements application tracing module which allows to send arbitrary
data to host over JTAG. This feature is useful for analyzing
program modules behavior, dumping run-time application data etc.
- Implements printf-like logging functions on top of apptrace module.
This feature is a kind of semihosted printf functionality with lower
overhead and impact on system behaviour as compared to standard printf.
spiflash ROM functions: Remove Quad I/O mode enable/disable code from flash ROM functions
Confusion here is that original ROM has two functions:
* SPIReadModeCnfig() - sets mode, calls enable_qio_mode/disable_qio_mode
* SPIMasterReadModeCnfig() - As above, but doesn't set QIO mode in status register
However we never want to use the ROM method to set/clear QIO mode flag, as not all flash chips work this way. Instead we
do it in flash_qio_mode.c in bootloader.
So in both cases (ROM or "patched ROM") we now call SPIMasterReadModeCnfig(), which is now named
esp_rom_spiflash_config_readmode().

Default CPU frequency option in Kconfig is set to 160MHz, pending qualification of 240MHz mode at high temperatures.
Register header files are moved into the new soc component, which will contain chip-specific header files and low-level non-RTOS-aware APIs (such as rtc_ APIs). Some of the files from ESP32 component were also moved: cpu_util.c, brownout.c, and the corresponding header files. Further refactoring of ESP32 component into more meaningful layers (chip-specific low level functions; chip-specific RTOS aware functions; framework-specific RTOS-related functions) will be done in future MRs.
