Fixes for omap variants for v5.3-rc cycle

We have another fix to disable voltage switching for am57xx SDIO as
the bootrom cannot handle all the voltages after a reset that thought
I had already sent a pull request for earlier but forgot. And we also
update dra74x iodelay configuration for mmc3 to use the recommended
values.

Then I noticed we had introduced few new boot warnings with the various
recent ti-sysc changes and wanted to fix those. I also noticed we still
have too many warnings to be able to spot the real ones easily and fixed
up few of those. Sure some of the warnings have been around for a long
time and few of the fixes could have waited for the merge window, but
having more usable dmesg log level output is a valuable.

Other fixes are IO size correction for am335x UARTs that cause issues
for at least FreeBSD using the same device tree file that checks that
the child IO range is not larger than the parent has.

For omap1 ams-delta keyboard we need to fix a irq ack that broke with
all the recent gpio changes.

And there are also few static checker warning fixes for recent am335x
PM changes and ti-sysc driver and one switch fall-though update.
