prd: Don't expose full opal_prd_msg to kernel
The kernel is only accessing part of struct opal_prd_msg, and doesn't
need to know about the rest. This change moves the "internal" parts of
opal_prd_msg to a separate header.
In order for the kernel to pass full messages between userspace and
firmware, it needs the total size of the struct. We put this in the
header for the kernel to access.
