Add bootcount support for Rockchip rk3399.
The bootcount value is preserved in PMU_SYS_REG0 register,
PMU_SYS_REG0 has been used by other case in Rockchip, we don't
Please ignore this mail, I mixing the registers in PMU and PMUGRF,
the PMU_SYS_REG0 is not used yet and you can use it.

recommend to use it, the PMUGRF_OS_REG3 is still reserved now, could you use it instead?

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.
