Change several entries of parent_data to use parent_hws instead, which
results in slightly more ovbious code.

The two devices managed by lpasscorecc-sc7180.c each had their own
"struct dev_pm_ops". This is not needed. They are exactly the same and
the structure is "static const" so it can't possible change. combine
the two. This matches what's done for sc7280.
This should be a noop other than saving a few bytes.

The sc7180 lpass clock controller's pm_runtime usage wasn't broken
quite as spectacularly as the sc7280's pm_runtime usage, but it was
still broken. Putting some printouts in at boot showed me this (with
serial console enabled, which makes the prints slow and thus changes
timing):
[ 3.109951] DOUG: my_pm_clk_resume, usage=1
[ 3.114767] DOUG: my_pm_clk_resume, usage=1
[ 3.664443] DOUG: my_pm_clk_suspend, usage=0
[ 3.897566] DOUG: my_pm_clk_suspend, usage=0
[ 3.910137] DOUG: my_pm_clk_resume, usage=1
[ 3.923217] DOUG: my_pm_clk_resume, usage=0
[ 4.440116] DOUG: my_pm_clk_suspend, usage=-1
[ 4.444982] DOUG: my_pm_clk_suspend, usage=0
[ 14.170501] DOUG: my_pm_clk_resume, usage=1
[ 14.176245] DOUG: my_pm_clk_resume, usage=0
...or this w/out serial console:
[ 0.556139] DOUG: my_pm_clk_resume, usage=1
[ 0.556279] DOUG: my_pm_clk_resume, usage=1
[ 1.058422] DOUG: my_pm_clk_suspend, usage=-1
[ 1.058464] DOUG: my_pm_clk_suspend, usage=0
[ 1.186250] DOUG: my_pm_clk_resume, usage=1
[ 1.186292] DOUG: my_pm_clk_resume, usage=0
[ 1.731536] DOUG: my_pm_clk_suspend, usage=-1
[ 1.731557] DOUG: my_pm_clk_suspend, usage=0
[ 10.288910] DOUG: my_pm_clk_resume, usage=1
[ 10.289496] DOUG: my_pm_clk_resume, usage=0
It seems to be doing roughly the right sequence of calls, but just
like with sc7280 this is more by luck than anything. Having a usage of
-1 is just not OK.
Let's fix this like we did with sc7280.

Use two new helpers instead of pm_runtime_enable() and pm_clk_create(),
removing the need for calling pm_runtime_disable and pm_clk_destroy().

and thus allow the device to autosuspend for 500ms.

The sc7180 lpass clock driver manages two different devices. These
two devices were tangled together, using one probe and a lookup to
figure out the real probe. I think it's cleaner to really separate
the probe for these two devices since they're really different things,
just both managed by the same driver.

Let's convert the lpass clock control driver to use devm. This is a
few more lines of code, but it will be useful in a later patch which
disentangles the two devices handled by this driver.

lpass_core_sc7180_probe() misses to call pm_clk_destroy() and
pm_runtime_disable() in error paths. Correct goto target to fix it.
This issue is found by code inspection.
