Subject: [PATCH v3 2/2] wifi: ath11k: support board-specific firmware overrides

QCA6698AQ IP core is the same as WCN6855 hw2.1, but it has different RF,
IPA, thermal, RAM size and etc, so new firmware files used. This change
allows board DT files to override the subdir of the firmware directory
used to lookup the amss.bin and m3.bin.

For example:

- ath11k/WCN6855/hw2.1/amss.bin,
  ath11k/WCN6855/hw2.1/m3.bin: main firmware files, used by default

- ath11k/WCN6855/hw2.1/qca6698aq/amss.bin,
  ath11k/WCN6855/hw2.1/qca6698aq/m3.bin

Tested-on: QCA6698AQ hw2.1 PCI WLAN.HSP.1.1-04479-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1
