From: Li Zhang <zhlcindy at linux.vnet.ibm.com>
PS2 device only works for X86 platform, other platforms may need
USB mouse. Athough it doesn't influence the QEMU command line, but
it's not right to add one PS2 mouse for non-X86 platform.
What's more, PS2 keyboard can be supported for X86.
So, this patch is to remove PS2 mouse for non-x86 platforms and also add
an implicit PS2 keyboard device for X86.
