crypto: ccp - Move some PSP mailbox bit definitions into common header
Some of the bits and fields used for mailboxes communicating with the
PSP are common across all mailbox implementations (SEV, TEE, etc).
Move these bits into the common `linux/psp.h` so they don't need to
be re-defined for each implementation.
