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.
