Updated the VMMOUSE macro to use the new VMW_PORT macro. Doing
this instead of replacing all existing instances of VMWMOUSE
to minimize code change.

v2:
Instead of replacing existing VMMOUSE defines, only modify enough
to use the new VMW_PORT define.

v3:
Use updated VMWARE_PORT() which requires hypervisor magic as an added
parameter

v4:
Swapped parameters 1 and 2 when calling VMW_PORT because the macro
has been updated
