bdbfd58974 clk: rockchip: rk3588: Add limited TMCLK_EMMC clock support
The device tree sdhci node reference the TMCLK_EMMC clock, add limited
support this clock to rk3588 cru driver. Fixes probe of sdhci driver.

6737771600 rockchip: rk3588: Add support for sdmmc clocks in SPL
Booting from sdmmc on RK3588 currently works because of a workaround in
the device tree, clocks are reordered so that the driver use ciu-sample
instead of ciu, and the BootRom initializes sdmmc clocks before SPL is
loaded into DRAM.

The sdmmc clocks are normally controlled by TF-A using SCMI. However,
there is a need to control these clocks in SPL, before TF-A has started.

This adds a rk3588_scru driver to control the sdmmc clocks in SPL before
TF-A has started, using scru regs. It also adds a small glue driver to
bind the scmi clock node to the rk3588_scru driver in SPL.
