Subject: [PATCH v3] drivers: net: Replace acpi_bus_get_device()

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Replace acpi_bus_get_device() that is going to be dropped with
acpi_fetch_acpi_dev().

While at it, rearrange the local variable definitions in
bgx_acpi_register_phy() and mdio-xgene.c:acpi_register_phy() so as
to put them in the reverse xmas tree order.

No intentional functional impact.

v2 -> v3: Fix a build issue and avoid changing the lists of local
          variables (Jakub Kicinski).

-> v2: Put local variable definitions in two functions in the reverse xmas
       tree order (Andrew Lunn).
