In ichiic(4), ignore the SMBALERT# interrupt. This interrupt has been
observed to fire for spurious reasons with buggy hardware/bios.
It is being ignored by both FreeBSD and Linux as well.
Fixes GENERIC kernel boot on ADI RCC-VE with buggy bios versions, where
ichiic(4) ended up stealing interrupts from ehci(4), rendering the internal
eMMC flash unusable.
Also, always ackknowledge all interrupts by writing status bits back
to avoid a potential SMBALERT# interrupt storm.
