All parts expect the SPLL to run at 702MHz. In U-Boot it's the SPLL_HZ
declaring this rate and in the kernel it's a fixed clock definition.
While everything is expecting 702MHz, the SPLL is not running that
frequency when coming from the bootrom though, instead it's running
at 351MHz and the vendor-u-boot just sets it to the expected frequency.
The SPLL itself is located inside the secure-BUSCRU and in theory
accessible as an SCMI clock, though this requires an unknown amount
of cooperation from trusted-firmware to set at a later stage, though
during the SPL stage we can still access the relevant CRU directly.
The SPLL is for example necessary for the DSI controllers to produce
output.
As the SPLL is "just" another rk3588 pll, just set the desired rate
directly during the SPL stage.
Tested on rk3588-rock5b and rk3588-tiger by reading back the PLL rate
and also observing working DSI output with this change.

The current DT bindings for the rk3588 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.
This approach has been implemented already in Linux, by commit :
f1c506d152ff ("clk: rockchip: add clock controller for the RK3588")
Hence, implement a similar approach using the lookup table, and adapt
the existing reset driver to work with SoCs using lookup table.
The file rst-rk3588.c has been copied as much as possible from Linux.
Adapt the clk rk3588 driver as well to bind the reset driver with the
lookup table.

The CRU is being probed with a default set of assigned clocks, which
are not implemented in the driver at all.
Hence, when clk_set_defaults is called, it fails with ENOENT.
This would not be a problem, as the CRU still handles all the required
clocks, and the assigned clocks are default configs which are preprogrammed
or not required for Uboot operations.
However, the rockchip reset driver is being bound by the same DT node
as CRU, as the reset driver has no DT node.
But, when probing the reset node, it will call again the clk_set_defaults
for the CRU node, and failing because of missing those specific clocks
in the rk3588 clock driver.
To avoid this, simply implement a basic set/get that will just return
success and the default corresponding rate for the required assigned clocks.
As those clocks were not supported in Uboot, not required for Uboot
operations, there is no need to do any different kind of initialization.

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.
