wifi: brcmfmac: add per-vendor feature detection callback
[ Upstream commit 14e1391b71027948cdbacdbea4bf8858c2068eb7 ]
Adding a .feat_attach() callback allowing per-vendor overrides
of the driver feature flags. In this patch the callback is only
provided by BCA vendor to disable SAE feature as it has not been
confirmed yet. BCA chips generally do not have the in-driver
supplicant (idsup) feature so they rely on NL80211_CMD_EXTERNAL_AUTH
to trigger user-space authentication.
