clk: sunxi-ng: add support for H6 PRCM CCU The H6 has clock/reset controls in PRCM part, like old SoCs such as H3 and A64. However, the PRCM CCU is rearranged; the register arragement is now similar to the main CCU of H6, and the PRCM now has two APB buses to control -- one is clocked from AHB clock derivde from AR100 clock, the other is clocked from the same mux with AR100 clock. Therefore a new driver is written for it. As there's no official document about the PRCM in H6, all the information are indirectly collected from BSP and parts of the document, and the information source is noted as comments in the driver's source code. If reliable information is provided furtherly, the driver needs to be rechecked. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

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.
