power: pmic: rk817: support rk817 pmic
The RK817 is a Power Management IC (PMIC) for multimedia and handheld devices. They contains the following components: - Regulators(4*BUCKs, 1* BOOST, 9*LDOs, 1*SWITCH) - RTC - Clocking Signed-off-by: Joseph Chen <chenjh@rock-chips.com> Signed-off-by: Elaine Zhang <zhangqing@rock-chips.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
