[PATCH v4 0/2] clk: clocking-wizard: add user clock monitor support

[Harry Austen]

Add support for the clock monitor functionality added in version 6.0 of the
Xilinx clocking wizard IP core, through use of devcoredump.

This is a follow up from a patchset I submitted quite a while ago [1],
where I was attempting to utilise the UIO subsystem instead. Stephen Boyd
suggested use of devcoredump instead [2] and I have finally got round to
giving this a go.

This is currently untested on hardware, so any help testing this would be
much appreciated!

v3 -> v4:
- Patches 1-4,8-9 dropped, as they were submitted/accepted separately [3]
- Patch 7 removed, as no longer creating a new UIO driver
- DT binding patch mostly unchanged. Slight rework and rebase, so removed
  Krzysztof's R-b tag just in case
- Clock monitor support patch now reworked to make use of devcoredump
- Rebased on top of clk-next
v2 -> v3:
- Move kernel doc variable comment to bottom in clk_hw transition patch (2)
- Remove extra line (and add Krzysztof's R-b tag) in binding patch (5)
- Add Krzysztof's A-b tag to dynamic reconfig binding patch (8)
v1 -> v2:
- Split and improve clk_hw+devres transition patch (2+3)
- Fix/improve DT binding patches (5+8)
- Utilise auxiliary bus in monitor support patch (6)
- Add dedicated UIO driver for monitor support (7)
