drm/i915/uc: fetch uc firmwares for each GT 



The FW binaries are independently loaded on each GT. On MTL, the memory
is shared so we could potentially re-use a single allocation, but on
discrete multi-gt platforms we are going to need independent copies,
so it is easier to do the same on MTL as well, given that the amount
of duplicated memory is relatively small (~500K).
