Subject: [PATCH] regmap: include <linux/delay.h> from include/linux/regmap.h

The readx_poll_timeout() macro calls usleep_range(), which is
declared in <linux/delay.h>.

Make include/linux/regmap.h include <linux/delay.h>, like
include/linux/iopoll.h does.  Otherwise, users of the macro
will see "implicit declaration of function 'usleep_range'" error.
