esp32: ets_update_cpu_frequency should set tick scale for both CPUs
ets_update_cpu_frequency ROM function updates g_ticks_per_us, which is has two copies, one for each CPU.
The APP CPU copy of g_ticks_per_us never got updated, resulting in shorter delays produced by ets_delay_us on the APP CPU.
This MR replaces ROM ets_update_cpu_frequency with a copy in IRAM which updates scaling factors on both of the CPUs.
So now we get expected delays (in microseconds):
```
ets_delay_us core=0 expected=50000 actual=50014
ets_delay_us core=1 expected=50000 actual=50015
vTaskDelay core=0 expected=50000 actual=49428
vTaskDelay core=1 expected=50000 actual=50000
```

SPI master driver
This merge requests adds an SPI Master driver. This driver is (of course) multithread capable, has device abstraction, has command queueing, DMA support and all other sorts of nice things you'd expect from a SPI driver.

modify bootloader dram start address, swap app bss and data segments
Modify bootloader dram_seg from address 0x3ffc0000 to 0x3fff0000, len from 0x20000 to 0x10000.
Also put app .data before .bss, to reduce the chance .data collides with ROM bootloader stack.

esp32: put .data before .bss
This change reduces chances that a large .bss segment will push .data all the way into
0x3ffe1320 — 0x3ffe5320 range where the bootloader stack is, creating a problem when
bootloader will be loading application into memory.
With this change, .data would need to be at least 200k big to cause problems.
