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 AZT2320. The ALSA snd-ad1818a driver also support the AZT2002 ID for MPU401 but this doesn't as I was unable to test it.
