Add support for registering unified (virtualized) planes, allowing SSPP
block to be allocated at runtime, during atomic_check. This allows
userspace app to use any plane without caring if it supports scaler or
YUV formats. All planes are marked as supporting all formats and scaler
options. The kernel space will select the appropriate SSPP pipe or
return an error if we run out of resources.
Virtual planes are disabled by default, use msm.dpu_use_virtual_planes=1
kernel parameter to enable them.
