soc/amd/common/include/spi: fix SPI_FIFO_LAST_BYTE define
The last byte of the SPI FIFO SPI_FIFO_LAST_BYTE is at offset 0xc6 of
the SPI controller's MMIO region for Stoneyridge and Picasso. Both
SPI_FIFO_LAST_BYTE and SPI_FIFO_DEPTH had an off-by-one error that ended
up cancelling out each other, so the resulting value for SPI_FIFO_DEPTH
isn't changed.
TEST=Timeless build results in identical image for Mandolin.
