xen: fix wrong SPDX headers of Xen related headers

Commit b24413180f5600 ("License cleanup: add SPDX GPL-2.0 license
identifier to files with no license") was meant to do a tree-wide
cleanup for files without any license information by adding a SPDX
GPL-2.0 line to them.

Unfortunately this was applied even to several Xen-related headers
which have been originally under the MIT license, but obviously have
been copied to the Linux tree from the Xen project without keeping the
license boiler plate as required.

Correct that by changing the license of those files back to "MIT".

Some files still contain the MIT license text. Replace that by the
related SPDX line.

xen: Sync up with the canonical protocol definitions in Xen

This is the sync up with the canonical definitions of the input,
sound and display protocols in Xen.

Changes to kbdif:
1. Add missing string constants for {feature|request}-raw-pointer
to align with the rest of the interface file.

2. Add new XenStore feature fields, so it is possible to individually
control set of exposed virtual devices for each guest OS:
- set feature-disable-keyboard to 1 if no keyboard device needs
to be created
- set feature-disable-pointer to 1 if no pointer device needs
to be created

3. Move multi-touch device parameters to backend nodes: these are
described as a part of frontend's XenBus configuration nodes
while they belong to backend's configuration. Fix this by moving
the parameters to the proper section.

Unique-id field:
1. Add unique-id XenBus entry for virtual input and display.

2. Change type of unique-id field to string for sndif to align with
display and input protocols.

xen pvfb: Para-virtual framebuffer, keyboard and pointer driver

This is a pair of Xen para-virtual frontend device drivers:
drivers/video/xen-fbfront.c provides a framebuffer, and
drivers/input/xen-kbdfront provides keyboard and mouse.

The backends run in dom0 user space.

The two drivers are not in two separate patches, because the
intermediate step (one driver, not the other) is somewhat problematic:
the backend in dom0 needs both drivers, and will refuse to complete
device initialization unless they're both present.
