Subject: [PATCH v2 0/5] LLCC: Support for Broadcast_AND region

This series adds:
1. Device tree register mapping for Broadcast_AND region in SM8450,
SM8550, SM8650.
2. LLCC driver updates to reflect addition of Broadcast_AND regmap.

To support CSR programming, a broadcast interface is used to program all
channels in a single command. Until SM8450 there was only one broadcast
region (Broadcast_OR) used to broadcast write and check for status bit
0. From SM8450 onwards another broadcast region (Broadcast_AND) has been
added which checks for status bit 1.

This series updates the device trees from SM8450 onwards to have a
mapping to this Broadcast_AND region. It also updates the llcc_drv_data
structure with a regmap for Broadcast_AND region and corrects the
broadcast region used to check for status bit 1.

Merging strategy
----------------

All patches should be merged due to LLCC DeviceTree/driver dependency.

Changes in v2:
- Added an additional check in the case old DT files are used for
above mentioned chipsets for backwards compatibility
- Moved addition of if check in llcc_update_act_ctrl() to a separate
"Fixes" patch; not part of this series
