Ilya Lipnitskiy b98d45f16e MIPS: pci-legacy: stop using of_pci_range_to_resource 
[ Upstream commit 3ecb9dc158 ]

Mirror commit aeba3731b1 ("powerpc/pci: Fix IO space breakage after
of_pci_range_to_resource() change").

Most MIPS platforms do not define PCI_IOBASE, nor implement
pci_address_to_pio(). Moreover, IO_SPACE_LIMIT is 0xffff for most MIPS
platforms. of_pci_range_to_resource passes the _start address_ of the IO
range into pci_address_to_pio, which then checks it against
IO_SPACE_LIMIT and fails, because for MIPS platforms that use
pci-legacy (pci-lantiq, pci-rt3883, pci-mt7620), IO ranges start much
higher than 0xffff.

In fact, pci-mt7621 in staging already works around this problem, see
commit 09dd629eea ("staging: mt7621-pci: fix io space and properly set
resource limits")

So just stop using of_pci_range_to_resource, which does not work for
MIPS.

Fixes PCI errors like:
  pci_bus 0000:00: root bus resource [io  0xffffffff]

Fixes: 0b0b0893d4 ("of/pci: Fix the conversion of IO ranges into IO resources")
