The newly added GRF types introduced kzalloc usage into the rk3528.
At least for the similar rk3576 driver, the kernel-test-robot reported the
missing prototype, which warranted adding a slab.h include.
While it did not complain about the rk3528, so the header might be included
"accidentially" right now, add a real include to make sure we keep it
included in the future.

These clocks locate in VO and VPU GRF, serving for SD/SDIO controller
tuning purpose. Add their definitions and register them in driver if
corresponding GRF is available.
GRFs are looked up by compatible to simplify devicetree binding.

In the commit 5d0eb375e6 ("clk: rockchip: Add clock controller driver
for RK3528 SoC") only the dt-binding header was added for the reset
controller for the RK3528 SoC.
Add a reset lookup table generated from the SRST symbols used by vendor
linux-6.1-stan-rkr5 kernel to complete support for the reset controller.

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.
