This is a new version of the series initially posted at [1], reworking
the vGIC and timer code to cope with the M1 braindead^Wamusing nature.

Not much has changed, except for the missing irq_ack callback when
taking a timer interrupt, which would leave a screaming interrupt.

Tested with multiple concurrent VMs running from an initramfs.

* From v1 [1]:
  - Rebased on Hector's v4 posting[0]
  - Dropped a couple of patches that have been merged in the above series
  - Fixed irq_ack callback on the timer path
