At long last, the day has come, and we can bury full-chip erase once and for all

Back in November 2008(!) I proposed the first version of the flexible
sector-based erase structure, and now we can finally rip out the old
full-chip erase code without ill effects. Rejoice and party!

Thanks to everyone who made this possible, especially to Sean Nelson who
converted the majority of flash chips to sector erase.

Corresponding to flashrom svn r895.
