iio: proximity: sx9500: Reference ACPI and OF ID data

Always reference acpi_device_id and of_device_id tables, as they is
little benefit of conditional compiling and OF table could be used also
for ACPI matching via PRP0001.  This fixes warning:

  drivers/iio/proximity/sx9500.c:1039:34: error: ‘sx9500_of_match’ defined but not used [-Werror=unused-const-variable=]
