This is an existing optional property that ieee80211.yaml/cfg80211
provides. It's useful to further restrict supported frequencies
for a specified device through device-tree.
The driver supported this since ~2017 by
commit 0f83ff697356 ("brcmfmac: use wiphy_read_of_freq_limits to respect limits from DT")
This property is already being used by:
arch/arm/dts/bcm4709-netgear-r8000.dts
