msm: mdss: Update MDP memory retention sequence for msmcobalt

Browse source 
msmcobalt requires MDP clks ON when configuring the retention bits of
MDSS_MDP_CBCR and MDSS_MDP_LUT_CBCR registers, so that the retention
signals can be propagated to memories. This change adds the code
to support the new requirement.
