045e50641f target/arm: Catch invalid kvm state also for hvf
Some features such as running in EL3 or running M profile code are
incompatible with virtualization as QEMU implements it today. To prevent
users from picking invalid configurations on other virt solutions like
Hvf, let's run the same checks there too.

7227de94ad ps2: remove update_irq() function and update_arg parameter
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().

5cbf35d20f lasips2: rename lasips2_init() to lasips2_initfn() and update it to return the LASIPS2 device
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.

c2b1747973 pckbd: replace irq_kbd and irq_mouse with qemu_irq array in KBDState
This allows both IRQs to be declared as a single qdev gpio array.

6beb79e11a ps2: add gpio for output IRQ and optionally use it in ps2_raise_irq() and ps2_lower_irq()
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.
