[ Upstream commit b40d022ec06ade9f6c809091dc188422a0f0946d ]
[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.
v2: use existing calculation of dram_speed_mts for now to avoid regression
