kernel.h: move READ/WRITE definitions to <linux/types.h> 

Patch series "kernel.h: Move out a couple of macros and constants".

kernel.h hosts a couple of macros and constants that may be better placed.
Do that.  Also add missing documentation.  No functional changes
intended.


This patch (of 2):

Headers shouldn't be forced to include <linux/kernel.h> just to
gain these simple constants.
