16 minors per MMC block device are required to boot Rinato (Gear 2)
board because up to 15 partitions are used.
With default 8 minors booting failed with:
[ 1.329092] mmcblk0: mmc0:0001 F5X5MA 3.64 GiB
[ 1.329448] mmcblk0boot0: mmc0:0001 F5X5MA partition 1 4.00 MiB
[ 1.329627] mmcblk0boot1: mmc0:0001 F5X5MA partition 2 4.00 MiB
[ 1.329808] mmcblk0rpmb: mmc0:0001 F5X5MA partition 3 512 KiB
[ 1.335717] mmcblk0: p1 p2 p3 p4 p5 p6 p7
[ 1.436553] Waiting for root device /dev/mmcblk0p15...
while the correct list of partitions on mmcblk0 for Gear 2 is:
[ 1.436651] mmcblk0: p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 p11 p12 p13 p14 p15
