[SeaBIOS] [PATCH] Fix qemu mouse Set_Protocol behavior

[Kevin O'Connor]

The QEMU USB mouse claims to support the "boot" protocol
(bInterfaceSubClass is 1).  However, the mouse rejects the
Set_Protocol command.

The qemu mouse does support the "boot" protocol specification, so a
simple fix is to just enable the Set_Portocol request.
