spi: fix the bug of connecting SPI peripheral to read-only pins

The requirements of pin capabilites is different for spi master and
slave. The master needs CS, SCLK, MOSI to be output-able, while slave
needs MISO to be output-able.

Previous code is for master only.

This commit allows to place other 3 pins than MISO on input-only pins
for slaves. Refactoring for spi_common is also included.

Resolves https://github.com/espressif/esp-idf/issues/2455
