kselftests: timers: Check _ALARM clockids are supported before suspending

It was reported that the alarmtimer-suspend test hangs on older
systems that don't support _ALARM clockids.

This is due to the fact that we don't check if the timer_create
fails, and thus when we suspend, the system will not programatically
resume.

Fix this by checking the timer_create call for errors.

kselftests: timers: Ease alarmtimer-suspend unreasonable latency value

On the hardware I have, resume latency from an alarm is often
2-3 seconds (with a fair amount of variability due to the RTC's
single second granularity). Having four seconds be the pass/fail
bar is maybe a little too tight, so extend this to 5 seconds.

kselftests: timers: Increase delay between suspends in alarmtimer-suspend

When testing on some hardware, waiting only a second before
re-triggering suspend can keep TCP connections from re-establishing
which after a number of cycles can cause TCP connections to close
while the test is running.

So extend the delay between suspend calls to 3 seconds to let
the connections stay alive.

That solves several merge conflicts:
Documentation/DocBook/media/v4l/subdev-formats.xml
Documentation/devicetree/bindings/vendor-prefixes.txt
drivers/staging/media/mn88473/mn88473.c
include/linux/kconfig.h
include/uapi/linux/media-bus-format.h

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.
