Add the clock and reset controller driver for the Rockchip RV1106,
based on the vendor kernel from the Luckfox Pico SDK [1] at commit
824b817f8 (a Linux 5.10.160 kernel tree), adapted to the upstream
clock framework.
The MMC drive and sample phase clocks have their control registers in
the GRF region. The CRU provides these clocks itself, using the syscon
referenced by the rockchip,grf property as an auxiliary regmap, in the
same way as the RK3528.
The RV1103 is a package variant of the RV1106 and uses the same CRU.

COMMON_CLK_ROCKCHIP already gates the Rockchip clock objects inside the
Rockchip clock Makefile. Allow selecting it for COMPILE_TEST and use it
for the parent Makefile descent instead of ARCH_ROCKCHIP.
The per-SoC Rockchip clock symbols already have COMPILE_TEST dependencies,
so this exposes the existing build coverage to other architectures without
selecting the Rockchip platform.
Tested with:
make LLVM=1 ARCH=loongarch drivers/clk/rockchip/

Add clock tree definition for RK3528. Similar to previous Rockchip
SoCs, clock controller of RK3528 is combined with the reset controller.
We omit the reset part for now since it's hard to test it without
support for other basic peripherals.

Add the clock and reset tree definitions for the new RK3576
SoC.
As opposed to the other rockchip CRU drivers, the GRF node is looked up
via compatible instead of a phandle, which simplifies the device tree
bindings.

Both of these drivers were converted to real drivers and got a tristate
build option. But them being builtin_platform_drivers, they only ever
should be build-in - as the name suggests.
So adapt the Kconfig symbol and drop the MODULE_* parts from the drivers.

As suggested by Stephen in the series adding the rk3568 clock controller
the depends works just as well without the parenthesis around the depends.
So to make everything look the same, drop them from existing entries too.
