drm/i915: Add lmem_bar_size modparam
For testing purposes, support forcing the lmem_bar_size through a new
modparam. In CI we only have a limited number of configurations for DG2,
but we still need to be reasonably sure we get a usable device (also
verifying we report the correct values for things like
probed_cpu_visible_size etc) with all the potential lmem_bar sizes that
we might expect see in the wild.
v2: Update commit message and a minor modification.(Matt)
v3: Optimised lmem bar size code and modified code to resize
bar maximum upto lmem_size instead of maximum supported size.(Nirmoy)
v4: Optimised lmem bar size code.(Nirmoy)
