[PATCH] iopoll: include <linux/ktime.h> instead of <linux/hrtimer.h>

From: Masahiro Yamada
Date: Tue Dec 13 2016 - 20:36:12 EST

The timer APIs this header needs are ktime_get(), ktime_add_us(),
and ktime_compare(). So, including <linux/ktime.h> seems enough.
This commit will cut unnecessary header file parsing.

I was not quite sure whom I should send this patch to.
I am sending this to Will Deacon because commit 54c523127bcc
("iopoll: Introduce memory-mapped IO polling macros") was applied
by him.
