ACPI: scan: Rename acpi_bus_get_parent() and rearrange it
The acpi_bus_get_parent() name doesn't really reflect the
purpose of the function so change it to a more accurate
acpi_find_parent_acpi_dev().
While at it, rearrange the code inside that function to make it
easier to read.
No intentional functional impact.
