loadtools/scripts: w220.{config,init} => chimei.{config,init}
Motorola W220, first touched by FreeCalypso in 2019-05, is an ODM phone
made by Chi-Mei, and its peculiar property of relevance to loadtools
is that it has XRAM on Calypso nCS3 instead of the usual nCS1 - which
matters for fc-xram. We are now discovering other Chi-Mei phones
including Sony Ericsson J120, and they share the same quirk of XRAM
on nCS3 - hence we rename this loadtools target from w220 to chimei.
