clk: Add SiFive FU540 PRCI clock driver Add driver code for the SiFive FU540 PRCI IP block. This IP block handles reset and clock control for the SiFive FU540 device and implements SoC-level clock tree controls and dividers. Based on code written by Wesley Terpstra <wesley@sifive.com> found in commit 999529edf517ed75b56659d456d221b2ee56bb60 of: https://github.com/riscv/riscv-linux Boot and PLL rate change were tested on a SiFive HiFive Unleashed board.
