mmc: core: Fix switch on gp3 partition
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

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
