Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.

new device support in terms of LoC, but there has been some cleanup
in the core as well as the usual minor clk additions to various
drivers.
Core:
- parent tracking has been simplified
- CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
- of_clk_init() doesn't consider disabled DT nodes anymore
- clk_unregister() had an error path bug squashed
- of_clk_get_parent_count() has been fixed to only return unsigned ints
- HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
New Drivers:
- NXP LPC18xx creg
- QCOM IPQ4019 GCC
- TI dm814x ADPLL
- i.MX6QP
Updates:
- Cyngus audio clks found on Broadcom iProc devices
- Non-critical fixes for BCM2385 PLLs
- Samsung exynos5433 updates for clk id errors, HDMI support,
suspend/resume simplifications
- USB, CAN, LVDS, and FCP clks on shmobile devices
- sunxi got support for more clks on new SoCs and went through a minor
refactoring/rewrite to use a simpler factor clk construct
- rockchip added some more clk ids and added suport for fraction dividers
- QCOM GDSCs in msm8996
- A new devm helper to make adding custom actions simpler (acked by Greg)

These checks for < 0 are impossible now that
of_clk_get_parent_count() returns an unsigned int. Change the
checks for == 0 and update the type.

Use the regmap coming from syscon to access the registers instead of using
pmc_read/pmc_write. This allows to avoid passing the at91_pmc structure to
the child nodes of the PMC.
The final benefit is to have each clock register itself instead of having
to iterate over the children.

Commit dca1a4b5ff ("clk: at91: keep slow clk enabled to prevent system
hang") added a workaround for the slow clock as it is not properly handled
by its users.
Now that the slow clock is taken properly by the drivers, this workaround
is not necessary anymore, revert it.

All slow clk users are not properly claiming it (get + prepare + enable)
before using it.
If all users properly claiming this clock release it, the clock is
disabled, but faulty users still depends on it, and the system hangs.
This fix prevents the slow clock from being disabled, and should solve the
hanging issue, but offending drivers should be patched to properly claim
this clock.

AT91 slow clk is a clk multiplexer.
In some SoCs (sam9x5, sama5, sam9g45 families) this multiplexer can
choose among 2 sources: an internal RC oscillator circuit and an oscillator
using an external crystal.
In other Socs (sam9260 family) the multiplexer source is hardcoded with
the OSCSEL signal.
