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

[Gustavo Sousa]

>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.
