soc/amd/common/block/psp/psp_gen2: use SMN access to PSP
Since we can't rely on the MMIO base address in the PSP_ADDR_MSR MSR to
access the PSP mailbox registers, switch to using the SMN mapping of the
PSP mailbox registers. The PSP SMN base address is taken from the amdgpu
driver in the Linux kernel.
BUG=b:229779018
TEST=Mandolin still boots successfully and there are no errors/warnings
about possibly PSP-related things.
