clk: add driver for the SiFive FU540 PRCI and PLLs it controls
Add a driver for the SiFive FU540 PRCI IP block, which handles clock and some device reset control for the SiFive FU540 chip. Also add a driver- independent library for the Analog Bits Wide-Range PLL (WRPLL), used by the PRCI driver to monitor and control the WRPLL instances on the FU540 chip.
Boot-tested on a SiFive HiFive Unleashed board, using BBL and the open-source FSBL with a mainline-focused DTB.
This third version incorporates changes requested by Stephen Boyd <sboyd@kernel.org> and Rob Herring <robh@kernel.org>.
This patch series is also available, along with the DT macro prerequisite patch, at:
