drm/msm/dpu: don't play tricks with debug macros

DPU debugging macros need to be converted to a proper drm_debug_*
macros, however this is a going an intrusive patch, not suitable for a
fix. Wire DPU_DEBUG and DPU_DEBUG_DRIVER to always use DRM_DEBUG_DRIVER
to make sure that DPU debugging messages always end up in the drm debug
messages and are controlled via the usual drm.debug mask.

I don't think that it is a good idea for a generic DPU_DEBUG macro to be
tied to DRM_UT_KMS. It is used to report a debug message from driver, so by
default it should go to the DRM_UT_DRIVER channel. While refactoring
debug macros later on we might end up with particular messages going to
ATOMIC or KMS, but DRIVER should be the default.
