clk: rockchip: add clock controller for the RK3588

Add full clock controller support RK3588.

[rebase, integrate fixes from Wyon and Finley, add missing frequencies
 to PLL lookup table, update commit message, add GATE_LINK clocks which
 downstream handles in its own driver with one DT node per clock]
