[Intel-gfx] [PATCH 1/2] drm/i915/mtl: Add the missing CPU transcoder mask in intel_device_info

[Radhakrishna Sripada <radhakrishna.sripada@intel.com>]

CPU transcoder mask is used to iterate over the available
CPU transcoders in the macro for_each_cpu_transcoder().

The macro is broken on MTL and got highlighted when audio
state was being tracked for each transcoder added in [1].

Add the missing CPU transcoder mask which is similar to ADL-P
mask but without DSI transcoders.
