Subject: [PATCH 2/4] input: evdev: Replace timeval with timespec64

struct timeval is not y2038 safe.

All references to timeval in the kernel will be replaced
by y2038 safe structures.
Replace all references to timeval with y2038 safe
struct timespec64 here.

struct input_event will be changed in a different patch.
