Include 4k/32k erase commands.

These were sourced from the MX25L128 datasheet and match up
with what is used in Linux mtd/devices/m25p80.c .

Using svn cp rather than cp to copy these files over had the benefit
of preserving their history. It had the problem that it also copied
over mergeinfo data. Since we're retiring the projects/mips branch,
I'm removing the svn:mergeinfo property from them all.

Merge from projects/mips to head by hand:

merge register definitions for mx25l flash.

- Add write support for mx25l flash chip
- Some minor style(9) fixes

- Add support for MX25Lxxx SPI flash (readonly atm)
