UBI: use debugfs for the extra checks knobs
This patch introduces debugfs support to UBI. All the UBI stuff is kept in the "ubi" debugfs directory, which contains per-UBI device "ubi/ubiX" sub-directories, containing debugging files. This file also creates "ubi/ubiX/chk_gen" and "ubi/ubiX/chk_io" knobs for switching general and I/O extra checks on and off. And it removes the 'debug_chks' UBI module parameters.
