pc: make vgabios exit port more useful
We've always listened on port 501 for vgabios panic messages. In the entire
time I've worked on QEMU, I've never actually seen a vgabios panic message :-)
If we change the semantics of this port a little bit, it makes it possible to
use it for more interesting use-cases. I chose this approach instead of adding
a new I/O port because it avoids having a guest visible change.
This change allows single-byte access to port 501 and also uses the value
written to construct an exit code.

usb/hid: add hid_pointer_activate, use it
HID reorganziation broke the usb tablet in windows xp. The reason is
that xp activates idle before it starts polling, which creates a
chicken-and-egg issue: We don't call hid_pointer_poll because there are
no pending events. We don't get any events because the activation code
in hid_pointer_poll is never executed and thus all pointer events are
routed to the PS/2 mouse by qemu.
Fix this by creating a hid_pointer_activate function and call it from
usb-hid when the guest sets the idle state.
The Bare ETRAX FS board was a fictive machine that I used when
developing the CRIS system emulation. Since we support the
real AXIS-dev88 developer boards, there is no reason to
keep the fictive one around.
This commit also removes the double registration of the axis-dev88
board.
