[PATCH] pm: runtime: fix timer_expires on 32bits arch

From: Grygorii Strashko
Date: Fri Sep 18 2020 - 12:55:41 EST

The commit 8234f6734c5d ("PM-runtime: Switch autosuspend over to using
hrtimers") switched PM runtime autosuspend to use hrtimers and all related
time accounting in ns, but missed update the struct
dev_pm_info->timer_expires to u64. This causes timer_expires value to be
truncated on 32bits architectures when assignment is done from u64 values:

|- dev->power.timer_expires = expires;

Hence, fix it by changing timer_expires type to u64.
