[PATCH] mailbox: PCC: make struct pcc_mbox_driver static

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The structure pcc_mbox_driver is local to the source and does not
need to be in global scope, so make it static.

Cleans up sparse warning:
drivers/mailbox/pcc.c:576:24: warning: symbol 'pcc_mbox_driver' was
not declared. Should it be static?
