Add MSI-X support and update driver documentation accordingly.
Add 2 new IOCTL commands:
- Allow to reconfigure driver IRQ type in runtime.
- Allow to retrieve current driver IRQ type configured.
Add IRQ type validation before executing the READ/WRITE/COPY tests.

This driver is a logical device which provides an
interface between the hypervisor and a management
partition. This interface is like a message
passing interface. This management partition
is intended to provide an alternative to HMC-based
system management.
VMC enables the Management LPAR to provide basic
logical partition functions:
- Logical Partition Configuration
- Boot, start, and stop actions for individual
partitions
- Display of partition status
- Management of virtual Ethernet
- Management of virtual Storage
- Basic system management
This driver is to be used for the POWER Virtual
Management Channel Virtual Adapter on the PowerPC
platform. It provides a character device which
allows for both request/response and async message
support through the /dev/ibmvmc node.

Some of the source code embedded in mei-client-bus.txt was indented
using spaces. This properly indents it with tabs and also removes a
single space that was placed in front of a closing curly brace.

Building mei-amt-version.o triggers a GCC warning:
Documentation/misc-devices/mei/mei-amt-version.c: In function 'main':
Documentation/misc-devices/mei/mei-amt-version.c:103:5: warning: 'acmd.fd' is used uninitialized in this function [-Wuninitialized]
if (cl->fd != -1)
^
Documentation/misc-devices/mei/mei-amt-version.c:443:21: note: 'acmd.fd' was declared here
struct amt_host_if acmd;
^
GCC is correct. See, the call chain that GCC detects must be
main()
amt_host_if_init()
mei_init()
mei_deinit()
But when we enter mei_deinit() struct amt_host_if acmd is still
unitialized. That makes the test for (effectively) amt_host_if->mei_cl->fd
bogus.
But it turns out that call of mei_deinit() isn't needed at all. All of
the members of mei_cl will be set later in mei_init() and none will be
used before they are set. So we can simply drop this call of
mei_deinit().

It should be left to the drivers to enable and disable the device on the
MEI bus when e.g getting probed.
For drivers to be able to safely call the enable and disable hooks, the
mei_cl_ops must be set before it's probed and thus this should happen
before registering the device on the MEI bus. Hence the mei_cl_add_device()
prototype change.
