[ Upstream commit 3b2fa0c92686562ac0b8cf00c0326a45814f8e18 ]
Some versions of SoC MT7621 have three PCI express hosts. Some boards make use of those PCI through the staging driver mt7621-pci. Recently PCI support has been removed from MT7621 Soc kernel configuration due to a build error. This makes imposible to compile staging driver and produces a regression for gnubee based boards. Enable support for PCI again but enable it only if staging mt7621-pci driver is selected.
