generic/3.10: rename mtd patches
- change patch numbers to group the related stuff together, - add mtd prefix where it is missing, - use hyphens in the patch names Signed-off-by: Gabor Juhos <juhosg@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@37974 3c298f89-4303-0410-b956-a3cf2f4a3e73
