[1/1] PCI: exynos: Fix section mismatch warning

add_pcie_port is called from probe which is annotated with __init.
add_pcie_port calls dw_pcie_host_init which is also annotated with
__init. Thus it makes sense to annotate add_pcie_port with __init
to avoid the following section mismatch warning:

WARNING: drivers/pci/built-in.o(.text.unlikely+0xf8): Section mismatch in reference from the function add_pcie_port() to the function .init.text:dw_pcie_host_init()
   The function add_pcie_port() references
   the function __init dw_pcie_host_init().
   This is often because add_pcie_port lacks a __init
   annotation or the annotation of dw_pcie_host_init is wrong.

Applied with Jingoo's ack to pci/host-exynos for v3.16, thanks!
