[PATCH v2 4/6] xen/arm: remove XEN_DOMCTL_CONFIG_GIC_NATIVE from the ABI

[Julian Vetter <julian.vetter@xxxxxxxxxx>]

From: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>

Now that nothing resolves or relies on GIC_NATIVE (the previous patch
moved that decision entirely into the toolstack and Xen's own dom0/
dom0less builders), drop it from the public ABI. Every caller must
now request a concrete GIC_V2 or GIC_V3.

This is an incompatible change for any toolstack still passing 0
(formerly GIC_NATIVE) expecting Xen to auto-select a version, so bump
XEN_DOMCTL_INTERFACE_VERSION.
