Subject: [PATCH 1/2] wireless-regdb: add support for US S1G channels

The 902-928MHz band is one of the US ISM bands, so follows
the same emission limits described in FCC part 15.

Subject: [PATCH 2/2] wireless-regdb: add 802.11ah bands to world regulatory domain

802.11ah does not have a band which intersects global
regulatory domains, so just add the possible range as
NO-IR to at least allow passive scan.
