wifi: mac80211_hwsim: advertise puncturing feature support
If userspace provides a puncturing bitmap via the NL80211_ATTR_PUNCT_BITMAP
attribute, the kernel with mac80211_hwsim driver currently rejects the
command with the error: "driver doesn't support puncturing", because the
driver does not advertise support for this feature.
At present, the following hwsim test cases utilize puncturing, but the
bitmap is not sent to the kernel. Instead, the puncturing information is
conveyed only through the beacon data:
* eht_5ghz_80mhz_puncturing_override_1
* eht_5ghz_80mhz_puncturing_override_2
* eht_5ghz_80mhz_puncturing_override_3
A future change in hostapd will begin configuring the puncturing bitmap
explicitly, which will cause these test cases to fail unless the driver
advertises support.
To address this, update mac80211_hwsim driver to advertise puncturing
feature support.
