PCI: kirin: Fix section mismatch warning

commit 6870b673509779195cab300aedc844b352d9cfbc upstream.

The PCI kirin driver compilation produces the following section mismatch
warning:

WARNING: vmlinux.o(.text+0x4758cc): Section mismatch in reference from
the function kirin_pcie_probe() to the function
.init.text:kirin_add_pcie_port()
The function kirin_pcie_probe() references
the function __init kirin_add_pcie_port().
This is often because kirin_pcie_probe lacks a __init
annotation or the annotation of kirin_add_pcie_port is wrong.

Remove '__init' from kirin_add_pcie_port() to fix it.
