[PATCH 4/6] PCI: keystone: Convert to using hierarchy domain for legacy interrupts

[Krzysztof Wilczyński]

Hi Kishon,

Thank you for sending the series over!

A few small nitpick, so feel free to ignore it.

Use "IRQ" in the message above.

Also, the error messages with both starting with upper- and lower- case
letter, not sure if this is because of dev_err() vs pr_err(), but if
there is no significance between these two methods, then it might be
nice to keep the style consistent.
