This serie enables WCN7850 on the Qualcomm SM8550 QRD
reference platform.
The WCN7850 is close to the WCN6855 but uses different
firmware names.

Changes in v3:
- Rebased on next-20230803 (including WCN3988 changes)
- Dropped DT patches to be sent in a separate serie
- Link to v2: https://lore.kernel.org/r/[email protected]
Changes in v2:
- Convert if/else and qca_is_*() macros by switch/case to simplify adding now BT SoCs
- Add bindings reviewed-by
- Link to v1: https://lore.kernel.org/r/[email protected]

Use switch/case to handle soc type specific behaviour,
the permit dropping the qca_is_xxx() inline functions
and maked the code clearer and easier to update for new
SoCs.
