This patchset adds support for the Microchip PolarFire clkcfg
hardware block.

Changes since v8:
* Use devm_clk_hw_unregister directly
* Get parent clk in probe rather than register function

Changes since v7:
* Dropped clock-output-names again (oops)

Changes since v6:
* Dropped clock-output-names *as a required property*
* Dropped if(lock) check on spinlocks, added spinlocks to all
  read-modify-write register access
* Removed kfree()s on non-dynamically allocated variables
* Use devm_clk_get to get the reference clock
* Account for reserved clock when calculating the size of num_clks

Changes since v5:
* Dropped clock-output-names property

Major changes since v4:
* Adjusted license for microchip,mpfs-clock.h to match microchip,mpfs.yaml
* Corrected the number of clocks to 33 from 32

Major changes since v3:
* Patch reformatted so microchip,mpfs-clock.h is part of device-tree patch

Major changes since v2:
* In mpfs_cfg_clk_set_rate, return immediately if divider_get_val
    returns <0 
* rebased to v5.12-rc1

Major changes since v1:
 * Dependency on SOC_MICROCHIP_POLARFIRE
 * All references to PFSOC/pfsoc changed to MPFS/mpfs
 * Cleaned error handling in _probe
 * Re-ordered code to place structs et al at top
