drm/rockchip: vop2: update dsc pd status when show logo with dsc

Browse Source 
In normal case, dsc power domain will enable when crtc enable and
disabled when crtc disable. When enable dsc in uboot to show logo,
the dsc in kernel driver can't know the real power domain status,
which will trigger something wrong when disable/endale dsc power
domain.
To avoid this issue, we check the dsc power domain status when
vop_initial. the dsc power domain get in vop_initial function
is enabled only when dsc is enabled in uboot and  enter into kernel
driver. It need to update dsc power domain status in this case.
