The 5 GHz channels are stored in one hw_features set with mode
HOSTAPD_MODE_IEEE80211A while the 6 GHz channels will need to stored in
a separate hw_features set (but with same mode HOSTAPD_MODE_IEEE80211A)
due to possibility of different HE capabilities being available between
the 5 GHz and 6 GHz bands.
Search through all hw_features sets whose mode is same as the input mode
while finding channel corresponding to the input frequency in
hw_get_channel_freq().

oper_chwidth is used for both VHT and HE here.

This adds checks to common code to verify supported bandwidth options
for each channel using nl80211-provided info. No support of additional
modes is added, just additional checks. Such checks are needed because
driver/hardware can declare more strict limitations than declared in the
IEEE 802.11 standard. Without this patch hostapd might select
unsupported channel and that will fail because Linux kernel does check
channel bandwidth limitations.

This functionality can be used outside wpa_set_disable_ht40(), so move
the generic part to a helper function.
