Subject: [PATCH 148/151] ath11k: add regdb.bin download for regdb offload
The regdomain is self-managed type for ath11k, the regdomain info is
reported from firmware, it is not from wireless regdb. Firmware fetch
the regdomain info from board data file before. Currently most of the
regdomain info has moved to another file regdb.bin from board data
file for some chips such as QCA6390 and WCN6855, so the regdomain info
left in board data file is not enough to support the feature which need
more regdomain info.
After download regdb.bin, firmware will fetch the regdomain info from
regdb.bin instead of board data file and report to ath11k. If it does
not have the file regdb.bin, it also can initialize wlan success and
firmware then fetch regdomain info from board data file.
Add download the regdb.bin before download board data for some specific
chip which support supports_regdb in hardware parameters.
download regdb.bin log:
