spi_slave: improve the timing configuration
...
SPI Slave
===========
- Correct the configuration of mode 0~3 using new config in the TRM
- Split the workaround for DMA in mode 0/2 out of normal config, to make it clear.
- Update timing and speed document for the SPI slave.

spi_slave: add valid check for DMA buffers
...
The DMA cannot receive data correctly when the buffer address is not
WORD aligned. Currently we only check whether the buffer is in the DRAM
region.
The DMA always write in WORDs, so the length arguments should also be
multiples of 32 bits.
A check is added to see whether the buffer is WORD aligned and has valid
length.
