Using DMA to load TF-A into SRAM fails when booting from eMMC on RK3588.
## Checking hash(es) for Image atf-3 ... sha256 error!

Rockchip emmc devices have a similar issue to Rockchip dwmmc devices,
where performing DMA to SRAM later causes issues with suspend/resume.
Allow us to toggle SDMA in SPL for sdhci similar to ADMA support, so we

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.

supporting new SoCs like H6 with a reorganized CCU. One of the resets is
referenced from the PHY node instead of the controller node, so it will
have to wait until the PHY code is factored out to a separate driver.

This driver is actually used for powerpc and m68k/ColdFire.
On ColdFire SoC's, interrupt flag get not set if IIEN flag (mbcr bit6,
interrupt enabled) is not set appropriately before each transfert.
As a result, the transfert hangs forever waiting for IIEN.
This patch set IIEN before each transfert, while considering this fix
as not harming powerpc arch.

The IS_ENABLED, which does not consider SPL build, should be replaced
by CONFIG_IS_ENABLED.
For the case that we only enable DM CLK for u-boot but not in SPL, the
IS_ENABLED(CONFIG_CLK) still returns true, then cause clock failure.
