[ Upstream commit 2460386bef0b9b98b71728d3c173e15558b78d82 ]

The kernel test robot reported a following issue:

>> drivers/net/ethernet/marvell/mvmdio.c:426:36: warning:
unused variable 'orion_mdio_acpi_match' [-Wunused-const-variable]
static const struct acpi_device_id orion_mdio_acpi_match[] = {
^
1 warning generated.

Fix that by surrounding the variable by appropriate ifdef.
