This patch make the write to be a operation, allow rk3568 uses a private register set function. Since the 2.5v is not used on RK3568, so the driver only set 1.8v [enable] + 3.3v [disable] for 1.8v mode 1.8v [disable] + 3.3v [enable] for 3.3v mode There is not register order requirement which has been cleared by our IC team.
