While RPMB partition requires special IOCTL

From: Andrew Gabbasov <andrew_gabbasov@mentor.com> Since RPMB area is accessible via special ioctl only and boot areas are unlikely to contain any partitions, exclude them all from listing in /proc/partitions. This will hide them from various user-level software (e.g. fdisk), thus avoiding unnecessary access attempts.
