This patch series implements workarounds for HW errata in Cavium's
ThunderX GICV3.

The first one is a gicv3 code update I sent a while ago and is a
prerequisit for patch #4. Patch #2 adds generic code to parse the hw
revision provided by an IIDR register value and runs specific code if
hw matches. This is used to implement the actual errata fixes in patch
#3 (gicv3) and #4 (gicv3-its).

  irqchip, gicv3-its: Read typer register outside the loop
  irqchip, gicv3: Add HW revision detection and configuration
