drm/i915/mtl: Add the missing CPU transcoder mask in intel_device_info
[ Upstream commit 6ece90e3665a9b7fb2637fcca26cebd42991580b ]
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.
