[PATCH 06/20] include: input: elan-i2c-ids: Mark 'elan_acpi_id' as __maybe_unused

Some drivers which include 'elan-i2c-ids.h' make use of
'elan_acpi_id', but not all do. Tell the compiler that this is
expected behaviour.

Fixes the following W=1 kernel build warning(s):

include/linux/input/elan-i2c-ids.h:26:36: warning: ‘elan_acpi_id’ defined but not used [-Wunused-const-variable=]
