I wonder if this should default to 'y' if SOC_MT7621 && PCI.

I cannot build if PCI_MT7621 is 'n' as pcibios_map_irq() is wanted but
not available.

I currently have the following patch, but maybe it should stay as
'tristate' - not sure.

Thanks,

Subject: [PATCH] staging: mt7621-pci: PCI driver is not optional when
 relevant.

The mt7621-pci driver must be enabled for SOC_MT7621 if PCI is
enabled, else a link failure results as pcibios_map_irq() is not
defined.

In any other circumstance, the driver is not relevant.
So make it non-selectable and provide an appropriate default.
