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.

# Chi-Mei phones (Motorola W220, Sony Ericsson J120, likely others) have
# a single-bank flash chip on nCS0 and XRAM on nCS3 instead of the usual nCS1.
# The timings are unknown, so we set a conservative WS=4.  The flash can be
# 8 MiB, so we need to enable ADD22.
