UBI: cleanup and simplify Kconfig
Cleanup the Kconfig for UBI by using menuconfig to enable/disable the entire driver. Remove the dependency checks for MTD_UBI and MTD_UBI_DEBUG by wrapping the options in if/endif blocks and remove any redundant checks. Remove all default n since that is the Kconfig default. Change menu "Additional UBI debugging messages" into a comment to remove one menu level.
