The x86-android-tablets code needs to be able to get a serdev_controller device from a PCI parent, rather then by the ACPI HID+UID of the parent, because on some tablets the UARTs are enumerated as PCI devices instead of ACPI devices. Split the code to walk the device hierarchy to find the serdev_controller from its parents out into a get_serdev_controller_from_parent() helper so that the x86-android-tablets code can re-use it.
