zynq: pcie: AXI PCIE Fix section mismatch

Fix section mismatch because of section warnings.

Warning:
WARNING: arch/arm/mach-zynq/built-in.o(.text+0x2c5c):
 Section mismatch in reference from the function xaxi_pcie_setup()
 to the function .devinit.text:xaxi_pcie_set_bridge_resource()
The function xaxi_pcie_setup() references
the function __devinit xaxi_pcie_set_bridge_resource().
This is often because xaxi_pcie_setup lacks a __devinit
annotation or the annotation of xaxi_pcie_set_bridge_resource is wrong.

WARNING: arch/arm/mach-zynq/built-in.o(.text+0x2c68):
 Section mismatch in reference from the function xaxi_pcie_setup()
 to the function .devinit.text:xaxi_pcie_process_bridge_OF_ranges()
The function xaxi_pcie_setup() references
the function __devinit xaxi_pcie_process_bridge_OF_ranges().
This is often because xaxi_pcie_setup lacks a __devinit
annotation or the annotation of xaxi_pcie_process_bridge_OF_ranges is wrong.
