soc/amd/phoenix: Disable CCP DMA in PSP Verstage
Some stalls are observed while using CCP DMA in PSP verstage -
especially with CBFS verification enabled. Also with RW CBFS
verification enabled, the entire firmware body is not loaded during
verstage for verification. Instead the files are verified as and when
they are loaded from CBFS. Hence the impact to boot time is reduced
since only few files are loaded during PSP verstage. Hence disable CCP
DMA in PSP verstage until the root cause is identified.
BUG=None
TEST=Build and boot to OS in Myst with CBFS verification enabled.
