disp: msm: sde: update idlepc handling for wfd display

Browse Source 
When wfd display is connected, qseed3 coefficient lut
programming is getting erased due to idle pc entry for wfd pipes.
On idlepc exit commit, plane properties are not reconfigured from
userspace since support is not present for writeback crtc. This patch
updates idle pc handling to avoid gdsc power off when writeback
crtc is connected.
