Added HS200 to improve EMMC throughput for dra72.
With HS200 ============== Read throughput ./dd if=/dev/mmcblk0 of=/dev/null bs=1M count=100 oflag=sync 100+0 records in 100+0 records out 104857600 bytes (105 MB) copied, 1.46028 s, 71.8 MB/s
Write throughput root@dra7xx-evm:/# ./dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=100 oflag=sync 100+0 records in 100+0 records out 104857600 bytes (105 MB) copied, 9.34884 s, 11.2 MB/s
