[PATCH v1 2/7] ACPI: enumeration: Update UART serial bus resource documentation

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

In some cases UART serial bus resource may be represented by struct
serdev_device.

 As both ACPI and Device Tree represent a tree of devices (and their
 resources) this implementation follows the Device Tree way as much as
 possible.

 This means that when ACPI_HANDLE(dev) returns non-NULL the device was
 enumerated from ACPI namespace. This handle can be used to extract other
