Partially revert

Commit
21550029f709072aacf3b90edd574e7d3021b400 removed the
PLATFORM_QUIRK_GIC_64K_STRIDE quirk and introduced a way to
automatically detect that the two GICC pages have a 64K stride.
However the heuristic requires that the device tree for the platform
reports a GICC size == 128K, which is not the case for some versions of
XGene.
Fix the issue by partially reverting
21550029f709072aacf3b90edd574e7d3021b400:
- reintroduce PLATFORM_QUIRK_GIC_64K_STRIDE for XGene
- force csize and vsize to SZ_128K if csize is initially 4K and if
PLATFORM_QUIRK_GIC_64K_STRIDE
Also add a warning in case GICC is SZ_128K but not aliased.
