Add additional SPI sector erase and chip erase command functions

Not all chips support all commands, so allow the implementer to select
the matching function. Fix a layering violation in ICH SPI code to be
less bad. Still not perfect, but the new code is shorter, more generic
and architecturally more sound.

TODO (in a separate patch): - move the generic sector erase code to
spi.c - decide which erase command to use based on info about the chip -
create a generic spi_erase_all_sectors function which calls the generic
sector erase function

Thanks to Stefan for reviewing and commenting.

Corresponding to flashrom svn r337 and coreboot v2 svn r3722.
