[PATCH rtw-next v3 1/5] wifi: rtw88: 8812a, 8814a: enable STBC for HT transmissions

[Ho Jie Feng <hjf3108@gmail.com>]

8812a and 8814a support STBC, enable it.

8822c will lose reporting TX STBC capability if efuse reports
only 1 path, but this is correct, since it in that case it doesn't
actually support STBC.
