Convert the PolarFire SoC clock driver to use regmaps instead of iomem
addresses as a preparatory work for supporting the new binding for this
device that will only provide the second of the two register regions, and
will require the use of syscon regmap to access the "cfg" and "periph"
clocks currently supported by the driver.

This is effectively a revert of commit 4da2404bb003 ("clk: microchip:
mpfs: convert cfg_clk to clk_divider") and commit d815569783e6 ("clk:
microchip: mpfs: convert periph_clk to clk_gate") as it resurrects the
ops structures removed in those commits, with the readl()s and
writel()s replaced by regmap_read()s and regmap_writes()s.
