drm/i915/cmtg: Modify existing hook to disable CMTG

Browse source

Earlier cmtg_disable() used to disable all instances of CMTG
which cannot handle individual request for specific CMTG instance.
Introduce cmtg_disable_all() which will disable all cmtg instances
and cmtg_disable() only disable specific instance.

v2:
- Use intel_de_rmw to simplify. [Uma]

v3:
- Add a code comment describing when cpu_transcoder should be used
instead of cmtg_transcoder. [Uma]
