Subject: [PATCH, net-next] qcom-emag: hide ACPI specific functions

A couple of functions in this file are only used when building with
ACPI enabled, leading to a build warning on most architectures:

drivers/net/ethernet/qualcomm/emac/emac-sgmii.c:284:25: error: 'qdf2400_ops' defined but not used [-Werror=unused-variable]
 static struct sgmii_ops qdf2400_ops = {
                         ^~~~~~~~~~~
drivers/net/ethernet/qualcomm/emac/emac-sgmii.c:276:25: error: 'qdf2432_ops' defined but not used [-Werror=unused-variable]
 static struct sgmii_ops qdf2432_ops = {

This hides all the unused functions by putting them into the
corresponding #ifdef.
