Subject: [PATCH v6 1/5] dt-bindings: arm: msm: Add llcc Broadcast_AND register

The LLCC block in SM8450, SM8550 and SM8650 have a new register
space for Broadcast_AND region. This is used to check that all
channels have bit set to "1", mainly in SCID activation/deactivation.

Previously we were mapping only the Broadcast_OR region assuming
there was only one broadcast register region. Now we also map
Broadcast_AND region.
