The pspv2_mbox struct contained an unnamed union that covered the 32
bits of the command register of the PSP v2 mailbox. Since the pspv2_mbox
struct is mainly used for hardware register accesses and the union part
is mostly used to access the different bits before/after writing/reading
the command register, split this functionality. For the register access
a command field is added to the pspv2_mbox struct instead of the unnamed
union and for accessing the separate bits of the command register a new
named union is added.

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.
