Input: vmmouse - disable vmmouse before entering suspend mode

Input: vmmouse - disable vmmouse before entering suspend mode

Currently, when trying to suspend and resume with VirtualPS/2 VMMouse
there is an error message after resuming:

psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6

and the mouse will no longer be operable, requiring full rescan to find a
another driver to use for the port.

This error is due to QEMU still generating PS2 events which the kernel is
not consuming until resume time, where they interfere with mouse
identification and ultimately resulting in an error getting
VMMOUSE_VERSION_ID.

Test scenario:

1) start virtual machine with qemu command "vmport=on"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in the kernel logs

Let's fix this by disabling the vmmouse in its reset handler. This will
notify qemu to stop vmmouse and remove the handler.

Input: vmmouse - remove port reservation

The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This
causes the port to be reserved by the APCI module as the system comes up,
making it unavailable to be reserved again by other drivers, thus
preserving this VMWare port for special use in a VMWare guest.

This port is designed to be shared among multiple VMWare services, such as
the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port
on its own.

The VMWare non-EFI BIOS does not do this to preserve compatibility with
existing/legacy VMs. It is known that there is small chance a VM may be
configured such that these ports get reserved by other non-VMWare devices,
and if this ever happens, the result is undefined.

Input: add vmmouse driver

VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU
guests. By removing the guest cursor and using the host as a guest cursor
the cursor movement appears instant although in reality there is some lag.
To be able to do this, the host's view of the cursor position must exactly
match the guest's view and an absolute pointer device is needed. Enter the
VMMouse. While the VMMouse driver has historically been an Xorg user-space
driver, implementing it as a kernel imput driver enables rootless Xorg and
new compositing display servers for VMware guests.
