[Xen-devel] [PATCH V3] arm/gic-v3: Fix ACPI probe fail on GICv4 hardware

The current driver ACPI probe fails on hardware which has GICv4
version, even though it is fully compatible to GICv3. This patch
fixed the issue by registering the same probe function for GICv4

Signed-off-by: Shanker Donthineni <shankerd@xxxxxxxxxxxxxx>
Changes since v2:
    - Keep it the GICv4 version number inside driver and export outside as 

Changes since v1:
    - Edit commit text.
    - Fix BUG() in xen/arch/arm/domain.c
