media: dt-bindings: qcom,sm8550-iris: Add X1P42100 compatible

Document the new compatible string "qcom,x1p42100-iris".

Unlike SM8550 where the BSE (Bitstream Engine) is clocked implicitly
via vcodec0_core, x1p42100 exposes a dedicated BSE clock vcodec0_bse
that requires explicit enable/disable and frequency configuration.
The SM8550 driver has no knowledge of this clock and therefore cannot
operate x1p42100 hardware correctly.
