reset: rockchip: implement rk3588 lookup table

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.
