[PATCH 02/13] drm/msm/hdmi: Create separate Makefile/Kconfig

[Archit Taneja]

The msm Makefile and Kconfig are getting conjusted. HDMI is going to
have more configs and files in the future to manage, which will make
managing these harder.

Move hdmi related stuff into separate Kconfig and Makefile.
