reset: rockchip: implement rk3576 lookup table

Browse Source 
The current DT bindings for the rk3576 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 follows the implementation done in the Linux-Kernel and also
how the rk3588 does this both in the Linux-Kernel as well as U-Boot.
