staging: vchiq_core: Factor out bulk transfer for blocking mode

Browse source 
Factor out bulk transfer for blocking mode into a separate dedicated
function bulk_xfer_blocking_interruptible(). It is suffixed by
"_interruptible" to denote that it can be interrupted and -EAGAIN
can be returned. It would be up to the users of the function to retry
the call in those cases.

Adjust the calls to vchiq-dev.c ioctl interface and vchiq_arm.c
for blocking bulk transfers.
