Series PCI: qcom: Add support for SC8280XP and SA8540P | expand

Commit Message

Johan Hovold July 14, 2022, 7:13 a.m. UTC 
Add the SC8280XP platform to the binding.

SC8280XP use four host interrupts for MSI routing so remove the obsolete
comment referring to newer chipsets supporting one or eight interrupts
(e.g. for backwards compatibility).
