Add support for 40 MHz in HE to hwsim, it has support
for it in HT and appears to be the only driver that
has lower bandwidth in HE than HT.

Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Note: this breaks two hwsim tests in hostap, but that's
due to the wpa_supplicant code to estimate throughput
being broken in HE/EHT cases by not taking into account
the operating bandwidth, only the capabilities.
