Each time a Group-enable bit gets flipped, the state of these bits
needs to be forwarded to the hardware. This is a pretty heavy
handed operation, requiring all vcpus to reload their GICv4
configuration. It is thus implemented as a new request type.
[note to myself]
... and the status are forwarded to HW by programming VGrp{0,1}En
fields of GICR_VPENDBASER when vPEs are made resident next time.
I've added something based on this comment to the commit message.

Thanks!
