sysfs: add attribute specification for /sysfs/devices/.../coredump



This patch adds the specification for /sysfs/devices/.../coredump
which allows user-space to trigger a device coredump obtaining
binary data from the device for (fault) analysis. It relies on
CONFIG_DEV_COREDUMP being enabled.

		What: /sys/devices/.../coredump
		Date: December 2017
		Contact: Arend van Spriel <aspriel@gmail.com>
		Description:
		The /sys/devices/.../coredump attribute is only present when the
		device is bound to a driver, which provides the .coredump()
		callback. The attribute is write only. Anything written to this
		file will trigger the .coredump() callback.

		Available when CONFIG_DEV_COREDUMP is enabled.
