iio: adc: ti-adc128s052: Be consistent with arrays

The ti-adc128s052 driver has NULL terminated ID arrays for the
of_device_id, spi_device_id and acpi_device_id. All of these are
terminated by having an empty string as the last member of an array.
Only the of_device_id array uses the /* sentinel */ comment.

It's better to be consistent.

This /* sentinel */ comment serves no real purpose these days as people
are used to seeing these ID lists terminated with an empty array
element.

Drop the /* sentinel */ from the of_device_id.
