disp: msm: sde: add checks for hfc feature enablement of demura

瀏覽代碼 
HFC feature of demura needs a skip blend plane to be set. If skip blend
plane is not set and HFC feature is requested to be enabled, driver
should skip turning on HFC demura feature. Change adds checks to ensure
that HFC is always enabled with skip blend plane staged.
