rockchip: add basic partitions support for rk3288

For compatibility with distro boot, fastboot, and mount the mmc deivce
to PC via usb mass storage feature, GPT partitions are essential.

You should write the partitions to mmc device prior to use above
feature.

=> gpt write mmc 1 $partitions
GPT successfully written to block device!
success!
