Subject: [PATCH v2 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.

The driver has removed all support for firmware-name, and no upstream
Device Tree files reference this property. Therefore, this patch
removes the property from the binding and marks it as obsolete.

This is a DT ABI-breaking change, but safe since there are no in-tree
users.

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- Updates the commit message to clearly state that the property is
  obsolete and the change is ABI-breaking but safe for upstream.
