[PATCH] zd1211rw: Allow channels 1-13 in Japan
Eric Goff found that he could not use his ZD1211 device which is
programmed for the Japan regulatory domain. It turns out that ZyDAS
deviate from the spec here: they do not use the newer Japan region code
(0x41) but their drivers do operate as if the newer Japan legal
frequency range is in effect.
