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.
