Add the reset lines for the Allwinner A733 SoC. These reset control bits
are integrated into the Bus Gate Reset (BGR) registers, typically
sharing the same register address with their corresponding bus clock
gates. Integrate them into the main CCU driver using the existing
sunxi-ng ccu_reset framework, allowing the CCU to also function as a
reset controller for the SoC.
