This is for callers who want micro-second precision but are not
waiting from the atomic context.
linux/time.h provides us with USEC_PER_MSEC that would help to break up
these large numbers better for human consumption.
2000 -> 2*USEC_PER_SEC
10 -> 10*USEC_PER_MSEC
Maybe:
#define wait_for_seconds(x) ((x)*USEC_PER_SEC)
#define wait_for_milliseconds(x) ((x)*USEC_PER_MSEC)
if (_wait_for((I915_READ(pp_stat_reg) & mask) == value,
wait_for_seconds(5) /* timeout */,
wait_for_millseconds(10) /* interval */))
There are only two callers where it would be a bit interesting so it
just feels like needless change to me at the moment. Better to keep the
established conventions for these two macros.

Note after the atomic conversion, we can also do the !atomic assert here
and kill the drm_can_sleep() check
Noted. Maybe I'll put a comment somewhere.
