[PATCH for master 1/2] MIPS: fix PCI quirk infrastructure build

[Antony Pavlov <antonynpavlov@xxxxxxxxx>]

The commit fc2c618c2038 ("pci: add quirk infrastructure")
adds necessary ld-script changes only for ARM architecture.
As a result, qemu-malta build fails:

     LD      barebox
    drivers/built-in.o: In function `pci_fixup_device':
