[Intel-gfx] [PATCH i-g-t v2 1/7] lib/igt_aux: Use provided autoresume delay for rtc wake

This stores the autoresume delay provided via igt_set_autoresume_delay
for use during suspend via rtc wake scheduling. This delay was
previously only used for pm_test suspendm while the function suggests
it should be applied to all autoresume cases.

There is also definitely a use case for configuring the rtc wake delay,
so this implements it.
