soc/amd/common/block/psp/psp_gen2: rename cmd_response to buffer

The cmd_response field in the pspv2_mbox struct is the buffer used to
pass data to the PSP and back to the x86 side, so rename it to buffer.
This also aligns the code a bit more with the reference code. Also
rename the wr_mbox_cmd_resp function to wr_mbox_buffer_ptr.
