> pSeries machines on POWER9 processors can run with the XICS (legacy)
> interrupt mode or with the XIVE exploitation interrupt mode. These
> interrupt contollers have different interfaces for interrupt
> management : XICS uses hcalls and XIVE loads and stores on a page.
> H_EOI being a XICS interface the enable_scrq_irq() routine can fail
> when the machine runs in XIVE mode.
> 
> Fix that by calling the EOI handler of the interrupt chip.
