[PATCH 2/2] PCI: dwc: Remove unused PCIE_ATU_UNR_* register definitions

[Hans Zhang]

The PCIE_ATU_UNR_* macros are not used anywhere in the kernel.  They
were presumably intended for unrolled iATU register access, but the
driver now uses the ATU_* macros and computes unrolled offsets via
ATU_UNROLL_BASE().

Remove these unused definitions. No functional change intended.
