kernel: mtd: allow partial block erase
This fixes error erasing partial mtd partition which does not start on eraseblock boundary and allows using fconfig to configure redboot on devices such as the Gateworks Cambria. Signed-off-by: Maciej Skrzypek <maciej.skrzypek@flytronic.pl> SVN-Revision: 41733
