[PATCH 04/14] drm/amd/display: pass calculated dram_speed_mts to dml2

[Zaeem Mohamed]

From: Charlene Liu <Charlene.Liu at amd.com>

[why]
currently dml2 is using a hard coded 16 to convert memclk to dram_speed_mts.
for apu, this depends on wck_ratio.

change to pass the already calculated dram_speed_mts from fpu to dml2.
