Cristian Ciocaltea 6ece49c569 spi: amd: Limit max transfer and message size 
Enabling the SPI CS35L41 audio codec driver for Steam Deck [1]
revealed a problem with the current AMD SPI controller driver
implementation, consisting of an unrecoverable system hang.

The issue can be prevented if we ensure the max transfer size
and the max message size do not exceed the FIFO buffer size.

According to the implementation of the downstream driver, the
AMD SPI controller is not able to handle more than 70 bytes per
transfer, which corresponds to the size of the FIFO buffer.

Hence, let's fix this by setting the SPI limits mentioned above.
