[PATCH] zd1211rw: Allow channels 1-13 in Japan

Browse source 
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.
