ASoC: Add basic 1277-EV1 Littlemill audio driver
The Littlemill audio card supports a number of pluggable miniboards,
normally for the WM8994 family of devices. As all these devices look
mostly the same from an external configuration point of view and are
runtime enumerable we can write a standard machine driver which will
work out of the box with any of them. Start doing that with the bare
bones of a driver, only supporting AIF1.
Future patches will flesh this out to be more fully featured.

m68k/mac: fix baboon irq disable and shutdown
The baboon_disabled hack is broken because it is missing an irq shutdown method. So releasing a Baboon irq kills the other Baboon irqs. But we don't really need this hack because we don't have media bay support and TREX uses a NuBus IRQ. Remove it.

m68k/mac: oss irq fixes
The IOP driver calls into the OSS driver to enable its IRQ. This undesirable coupling between drivers only exists because the OSS driver doesn't correctly handle all of its machspec IRQs.
Fix OSS handling of enable/disable for VIA1 IRQs (8 thru 15) which includes MAC_IRQ_ADB.
Back when I implemented pmac_zilog support I redefined IRQ_MAC_SCC incorrectly. Change this to a machspec IRQ so that it works on OSS.
Clean up the unused OSS audio IRQ and OSS_IRQLEV_* cruft that only confuses things.
Fix the OSS description in macints.c and remove an obsolete comment.
Don't enable the VIA1 irq before registering the handler.

Enable via_alt_mapping on the Performa 588 and tidy up related documentation.
I'm betting that remapped IRQs work just fine on the Performa 580 series since it works on the LC 630 and the logic board part numbers are reputedly the same.
And the consensus seems to be that the Mac TV is essentially a Performa 550, not dissimilar to the Performa 520, so set the via_type accordingly.

Don't over-schedule QSFP work on driver initialization. It could end
up being run simultaneously on two different CPUs resulting in bad
EEPROM reads. In combination with setting the physical IB link state
prior to the IBC being brought out of reset, this can cause the link
