soc/amd/psp_verstage: Init TPM on S0i3 resume
Add option to initialize the TPM in PSP verstage during s0i3 resume.
This is needed if the TPM is reset in s0i3. FSDL is handling
restoring everything else, so only the minimum TPM initialization is done.
Move aoac and i2c init before psp_verstrage_s0i3_resume becasue i2c
needs to be ready before attempting to restore tpm.
BUG=b:200578885,b:197965075
TEST=Multiple cycles of S0i3 suspend resume. ~66ms of additional delay.
BRANCH=None
