soc/amd/sabrina: Enable PSP Crypto Co-Processor (CCP) DMA
Boot issue while using FW slot A has been root-caused to the usage of
same TLB to map HW Crypto engines and SPI flash. With upcoming PSP
release, this TLB usage conflict has been resolved. Hence enable CCP
DMA.
BUG=b:240175446
TEST=Build and boot to OS in Skyrim with PSP verstage using CCP DMA.
