patch from fixeria: doc change from SE K2x0 to K2xx Since their discovery in late 2022, Sony Ericsson K200 and K220 phones were collectively referred to as SE K2x0 in FreeCalypso documentation. However, now that SE K205 has been discovered as yet another member of the same family (same PCBA in different case), it makes more sense to refer to the whole family as SE K2xx.
