drm/i915: Make sure dsm_size has correct granularity
DSM granularity is 1MB so make sure we stick to that.
The address set by firmware in GEN12_DSMBASE in driver initialization
doesn't mean "anything above that and until end of lmem is part of DSM".
In fact, there may be a few KB that is not part of DSM on the end of
lmem. How large is that space is platform-dependent, but since it's
always less than the DSM granularity, it can be simplified by simply
aligning the size down.
v2: replace "1 * SZ_1M" with SZ_1M (Andrzej).
v3: reword commit message to explain why the round down is needed
