clk: sunxi-ng: h6-r: Add R_APB2_RSB clock and reset
While no information about the H6 RSB controller is included in the datasheet or manual, the vendor BSP and power management blob both reference the RSB clock parent and register address. These values were verified by experimentation. Since this clock/reset are added late, the specifier is added at the end to maintain the existing DT binding. The code is kept in register order.
