msm: mdss: Fix clk warnings for esc clk with dual-dsi panels 



In current implementation if dual-dsi panel's continuous splash screen
feature is enabled then feature flag is disabled only for master and
not for secondary panel. This leads to clk prepare without clk set rate.
For esc clk this leads to clk warning back-trace in the logs. For other
clocks, if clk rate changes between suspend/resume then it will lead to
rate incorrect programming and unknown behaviour. Fix this by disabling
secondary panel's feature flag.
