We have a stub defined for the acpi_dev_get_first_match_dev() in acpi.h
for the case when CONFIG_ACPI=n.

Moreover, acpi_dev_put(), counterpart function, is already placed under
CONFIG_ACPI.

Thus, move acpi_dev_get_first_match_dev() under CONFIG_ACPI as well.

Fixes: 817b4d64 ("ACPI / utils: Introduce acpi_dev_get_first_match_dev() helper")
