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.
