Instead of checking the response flag, use status mask also to check
against any unexpected failures like a device drop. Also, log error if
waiting on a psp response fails/times out.

Expose the debugfs file node for user space to dump the IFWI image
on spirom.

For one transaction between PSP and host, it will read out the
images on both active and inactive partitions so a buffer with two
times the size of maximum IFWI image (currently 16MByte) is needed.

v2: move the vbios gfl macros to the common header and rename the
    bo triplet struct to spirom_bo for this specific usage (Hawking)

v3: return directly the result of last command execution (Lijo)

VFs on some IP versions are unable to access this register directly.

This register must be programmed before PSP ring is setup,
so use PSP VF mailbox directly. PSP will broadcast the register
value to all VF assigned instances.
