rockchip: rk3399: Add bootcount support
Add bootcount support for Rockchip rk3399.
The bootcount value is preserved in PMU_SYS_REG0 register,
this would help to support redundent boot.
Once the redundant boot triggers, the altboot command
will look for extlinux-rollback.conf on particular
bootable partition which supposed to be a recovery
partition where redundant boot required.
