Now that all the PS2 devices have been converted to use GPIOs the update_irq()
callback function and the update_arg parameter can be removed.
This allows these arguments to be completely removed from ps2_kbd_init() and
ps2_mouse_init(), along with the transitional logic that was added to
ps2_raise_irq() and ps2_lower_irq().

Define a new qdev input gpio for handling incoming PS2 IRQs, and then wire up the
PS2 keyboard and mouse devices to use it. At the same time set update_irq() and
update_arg to NULL in ps2_kbd_init() and ps2_mouse_init() to ensure that any
accidental attempt to use the legacy update_irq() function will cause a NULL
pointer dereference.

Add a qdev gpio input in lasips2_init() by taking the existing lasips2_port_set_irq()
function, updating it accordingly and then renaming to lasips2_set_irq(). Use these

This can be improved once the ps2_kbd_init() and ps2_mouse_init() functions have
been removed, but for now move the existing logic from lasi_initfn() to
lasi_init(). At the same time explicitly set keyboard port id to 0, even if it
isn't technically required.

When QOMifying a device it is typical to use _init() as the suffix for an
instance_init function, however this name is already in use by the legacy LASIPS2
wrapper function. Eventually the wrapper function will be removed, but for now
rename it to lasips2_initfn() to avoid a naming collision.
At the same time update lasips2_initfn() return the LASIPS2 device so that it
can later be accessed using qdev APIs by the HPPA machine.

Define the gpio for the PS2 output IRQ in ps2_init() and add logic to optionally
use it in ps2_raise_irq() and ps2_lower_irq() if the gpio is connected. If the
gpio is not connected then call the legacy update_irq() function as before.
This allows the incremental conversion of devices from the legacy update_irq()
function to use gpios instead.

Since PS2_MOUSE_DEVICE is a qdev device then vmstate_ps2_mouse can be registered
using the DeviceClass vmsd field instead. There is no need to use
qdev_set_legacy_instance_id() to ensure migration compatibility since the first 2
parameters to vmstate_register() are NULL and 0 respectively.
