__usbhs_for_each_pipe() is the macro which moves around each pipe,
but it has a bug which didn't care about 1st pipe's position.
Because of this bug, it moves around
pipe0, pipe2, pipe3 ... even though it requested pipe1, pipe2, pipe3...
This patch modifies it.

Without this condition, all controllers will do this delay,
and increase the resume time.
Only enabled and unsuspended port needs this delay, but
Some buggy hardware(like Synopsys usb controller) will
clear suspend bit once they receive/send resume signal,
so it takes resume bit as consideration.
