[PATCH v4 ath-current 0/2] wifi: ath11k: add usecase firmware handling based on device compatible

The 'firmware-name' property was introduced to allow end-users and
integrators to select use-case-specific firmware for the WCN6855.
But for M.2 WLAN chips, there is no suitable DTS node to specify
the 'firmware-name' property. In addition, assigning firmware for
the M.2 PCIe interface causes chips that do not use use-case-specific
firmware to fail. Therefore, abandoning the approach of specifying
firmware in DTS. As an alternative, propose a static lookup table
mapping device compatible to firmware names.

---
v2:
- Drops `firmware-name` from completely.
- Updates the commit message to clearly state that the property is
  obsolete and the change is ABI-breaking but safe for upstream.
v3:
 - Deprecate 'firmware-name' property instead of obsolete.
 - Keep the ABI backwards compatible.
v4:
 - Use of_machine_is_compatible() to simplify the code.
 - Add back Acked-by tag.
