crypto: marvell/cesa - factor out first fragment decisions to helper
Multiple locations in the driver test the operation context fragment
type, checking whether it is a first fragment or not. Introduce a
mv_cesa_mac_op_is_first_frag() helper, which returns true if the
fragment operation is for a first fragment.
