It appears that some platforms share same IRQ line between several devices,
some of which are EHCI and OHCI controllers. This is neither practical nor
performance-wise, especially in the case when they are supporting MSI.

In order to improve the situation try to allocate MSI and fallback to legacy
IRQ if no MSI available.
