[PATCH v3 2/2] Bluetooth: btnxpuart: Update firmware names

From: Neeraj Sanjay Kale
Date: Wed May 29 2024 - 05:56:58 EST


This updates the firmware names of 3 chipsets: w8987, w8997, w9098.
These changes are been done to standardize chip specific firmware
file names.
To allow user to use older firmware file names, a new device tree
property has been introduced called firmware-name, which will override
the hardcoded firmware names in the driver.

v2: Remove "nxp/" from all firmware name definitions to be inline with
firware file name read from device tree file. (Krzysztof)
