clk: sunxi: Add Kconfig options We used to have a clock framework that isn't really used these days, except for a few clocks and/or SoCs. Most of the time, the new framework and drivers (sunxi-ng) will provide everything needed for the customer devices to operate properly. Since we're not needing it that much, it might make sense to disable those drivers, for example when we want to reduce the kernel size. Let's add options in Kconfig that can be disabled if needed, but are still on by default to keep the same features in the standard case.

bool "Legacy clock support for Allwinner SoCs"
clk: sunxi: Limit legacy clocks to 32-bit ARM The sunxi legacy clocks were never compatible with any 64-bit SoC, so there is no point in building them as part of a 64-bit ARM kernel. They make even less sense being built in to a 64-bit RISC-V kernel.

bool "Legacy clock drivers"
default y
help
Legacy clock drivers being used on older (A10, A13, A20,
A23, A31, A80) SoCs. These drivers are kept around for
Device Tree backward compatibility issues, in case one would
still use a Device Tree with one clock provider by
node. Newer Device Trees and newer SoCs use the drivers
controlled by CONFIG_SUNXI_CCU.

Legacy clock driver for the A31 PRCM clocks. Those are
usually needed for the PMIC communication, mostly.

help
Legacy clock driver for the sun8i family PRCM clocks.
Those are usually needed for the PMIC communication,
mostly.

Legacy clock driver for the A80 PRCM clocks. Those are
