MIPS: ralink: enable PCI support only if driver for mt7621 SoC is selected

Browse Source 
[ 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.
