This adds support for the two ICST525-based clocks on the
Integrator/AP baseboard, as documented in the board manual
"Integrator/AP ASIC Development Motherboard", ARM DUI0098 B,
pages 3-15 thru 3-18.

__of_clk_get_hw_from_provider() is confusing because it will
return EPROBE_DEFER if there isn't a ->get() or ->get_hw()
function pointer in a provider. That's just a bug though, and we
used to NULL pointer exception when ->get() was missing anyway,
so let's make this more obvious that they're not optional. The
assumption is that most providers will implement ->get_hw() so we
only fallback to the ->get() function if necessary. This
clarifies the intent and removes any possibility of probe defer
happening if clk providers are buggy.

In the commit 929e7f3b ("clk: Make of_clk_get_parent_count() return

for configs without CONFIG_OF. For the consistency it should be updated
as well.

The Integrator/AP and Integrator/CP have special derivatives
of the ICST525 control registers, where some bits have been
hardwired but others are possible to adjust, resulting in a
control register that makes it possible to set an even,
desired megahertz value.

The Integrator/AP and Integrator/CP have slightly different
layout so we support them using different compatible
strings.

After adding these clocks, the Integrator-specific cpufreq
driver can be switched over to use the generic operating
point device tree cpufreq driver.

Instead of simply writing a value to the oscillator control
register we switch to the more elaborate method of providing
a bitmask and use regmap_update_bits() to poke the right bits
for the desired frequency, this is needed since these control
registers sometimes control more than one clock.

We don't have code to handle any of the noc clocks in rk3399 and they're
all just listed as critical clocks.  Let's do the same for
aclk_emmc_noc.

Without this clock being marked as critical we have problems around
suspend/resume after commit 20c389e6 ("clk: rockchip: fix incorrect
aclk_emmc source gate bits on rk3399").  Before that change we were
presumably not actually gating any of these clocks because we were
setting the wrong gate.

Tegra114 has a HW bug that the PLLD/PLLD2 lock bit cannot be asserted when
the DIS power domain is during up-powergating process but the clamp to this
domain is not removed yet. That causes a timeout and aborts the power
sequence, although the PLLD/PLLD2 has already locked. To remove the false
alarm, we don't use the lock for PLLD/PLLD2. Just wait 1ms and treat the
clocks as locked.
