s25f.c: implement probing and block erasers for Spansion
This adds support for Spansion 25Fxxxxx chips. These chips
require their own probing logic because the first 6 bytes
returned by RDID must be examined to identify the chip.
New erase functions are required as the chips support multiple
sector layouts, and the default layout must be changed to be
able to erase the entire flash.
