iio: light: ltr501: Drop ACPI_PTR() usage

Avoiding unused variable warnings when using this macro adds
complexity that in simple cases like this one is not justified
for the small saving in data.

Include linux/mod_devicetable.h which includes the definition of
struct acpi_device_id (hence somewhat related to the main change)
