Arvind Ram Prakash 24a4a0a5ec fix(gic600): workaround for Part 1 of GIC600 erratum 2384374
GIC600 erratum 2384374 is a Category B erratum. Part 1 is fixed
in this patch, and the Part 1 failure mode is described as
'If the packet to be sent is a SET packet, then a higher priority SET
may not be sent when it should be until an unblocking event occurs.'

This is handled by calling gicv3_apply_errata_wa_2384374() in the
ehf_deactivate_priority() path, so that when EHF restores the priority
to the original priority, the interrupt packet buffered
in the GIC can be sent.

gicv3_apply_errata_wa_2384374() is the workaround for
the Part 2 of erratum 2384374 which flush packets from the GIC buffer
and is being used in this patch.
