soc/amd/picasso/psp: move soc_get_mbox_address to common PSP gen2 code

Browse Source 
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.
