Re: [Xen-devel] [PATCH 6/7] ARM: vGICv3: always use architected redist stride

Since we emulate the GICv3 distributor even for Dom0, we don't need to
copy the broken behaviour. All the special handling for Dom0s using
GICv3 is just for using the hardware's memory map, which is unaffected
by the redistributor stride - it can never be smaller than the
architected two pages.

Do we want a BUG_ON() just in case?

Remove the redistributor-stride property from Dom0's DT node and also
remove the code that tried to reuse the hardware value for Dom0's GICv3
