[PATCH] drm/i915/gsc: ARL-H and ARL-U need a newer GSC FW.

All MTL and ARL SKUs share the same GSC FW, but the newer platforms are
only supported in newer blobs. In particular, ARL-S is supported
starting from 102.0.10.1878 (which is already the minimum required
version for ARL in the code), while ARL-H and ARL-U are supported from
102.1.15.1926. Therefore, the driver needs to check which specific ARL
subplatform its running on when verifying that the GSC FW is new enough
for it.
