dt-bindings: net: wireless: ath11k-pci: describe firmware-name property

Introduce 'firmware-name' property to allow end-users and/or integrators
to decide which usecase-specific firmware to run on the WCN6855. This is
necessary due to resource limitations such as memory capacity and
CPU capability, or performance and power optimization for different
application scenarios.

Two firmwares are supported: 'WCN6855/hw2.0' and 'WCN6855/hw2.0/nfa765'.
The former is the default firmware, suitable for most WiFi 6 STA
functions. The latter adds support for commercial-quality SAP and
optimizes power consumption for IoT applications.
