soc/amd/picasso/psp: move soc_get_mbox_address to common PSP gen2 code
The function to get the PSP mailbox address is the same on Picasso and
Cezanne, so move it to the common PSP generation 2 code. The function is
only used in the same compilation unit, but it can't be marked as static
due to the function prototype in amdblocks/psp.h that is still needed
for Stoneyridge.
