Fixes for omaps for v5.8

The recent display subsystem (DSS) related platform data changes caused
display related regressions for suspend and resume. Looks like I only
tested suspend and resume before dropping the legacy platform data, and
forgot to test it after dropping it. Turns out the main issue was that
we no longer have platform code calling pm_runtime_suspend for DSS like
we did for the legacy platform data case, and that fix is still being
discussed on the dri-devel list and will get merged separately. The DSS
related testing exposed a pile other other display related issues that
also need fixing though:

- Fix ti-sysc optional clock handling and reset status checks
  for devices that reset automatically in idle like DSS

- Ignore ti-sysc clockactivity bit unless separately requested
  to avoid unexpected performance issues

- Init ti-sysc framedonetv_irq to true and disable for am4

- Avoid duplicate DSS reset for legacy mode with dts data

- Remove LCD timings for am4 as they cause warnings now that we're
  using generic panels

Then there is a pile of other fixes not related to the DSS:

- Fix omap_prm reset deassert as we still have drivers setting the
  pm_runtime_irq_safe() flag

- Flush posted write for ti-sysc enable and disable

- Fix droid4 spi related errors with spi flags

- Fix am335x USB range and a typo for softreset

- Fix dra7 timer nodes for clocks for IPU and DSP

- Drop duplicate mailboxes after mismerge for dra7
