[PATCH] mmc: card: Don't show eMMC RPMB and BOOT areas in /proc/partitions

[Harish Jenny K N]

From: Andrew Gabbasov <andrew_gabbasov@xxxxxxxxxx>

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.
