PNP: add ISAPnP MPU option quirks.

The AD181x and AZT230 chips don't support an IRQ-less MPU401 option
but work fine without one. This adds (priority functional) IRQ-less
options for each port option to help systems with few available IRQs.

The AD1815 quirk can't use pnp_register_irq_resource() due to doubly
penalizing the IRQ. Also, while not a practical issue due to no IRQ
option being present for the dependents, this needs to add in front,
not back.

Doesn't use pnp_register_port_resource() for symetry with above.

This does not delete the AD1815 independent option even though it
should be empty after the IRQ transfer due to AD1816 coming with an
empty but still present independent option by default.

Was tested on AD1815, AD1816 and AZT230. The ALSA snd-ad1818a driver

Typo: AZT2320

also support the AZT2002 ID for MPU401 but this doesn't as I was
unable to test it.
