Dominique Martinet 5fd111dcb7 mmc: core: Fix switch on gp3 partition 
[ Upstream commit 4af59a8df5ea930038cd3355e822f5eedf4accc1 ]

Commit e7794c14fd73 ("mmc: rpmb: fixes pause retune on all RPMB
partitions.") added a mask check for 'part_type', but the mask used was
wrong leading to the code intended for rpmb also being executed for GP3.

On some MMCs (but not all) this would make gp3 partition inaccessible:
armadillo:~# head -c 1 < /dev/mmcblk2gp3
head: standard input: I/O error
armadillo:~# dmesg -c

[  423.408287] Buffer I/O error on dev mmcblk2gp3, logical block 0, async page read

the part_type values of interest here are defined as follow:
main  0
boot0 1
boot1 2
rpmb  3
gp0   4
gp1   5
gp2   6
gp3   7

so mask with EXT_CSD_PART_CONFIG_ACC_MASK (7) to correctly identify rpmb
