PCI: hisi: Fix deferred probing
The hisi_pcie_probe() function is incorrectly marked as __init, as Kconfig tells us: WARNING: drivers/pci/host/built-in.o(.data+0x7780): Section mismatch in reference from the variable hisi_pcie_driver to the function .init.text:hisi_pcie_probe() If the probe for this device gets deferred past the point where __init functions are removed, or the device is unbound and then reattached to the driver, we branch into uninitialized memory, which is bad. Remove the __init annotation from hisi_pcie_probe() and hisi_add_pcie_port().
