[PATCH v1 1/1] iio: light: ltr501: Drop most likely fake ACPI ID

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

The commit in question does not proove that ACPI ID exists.
Quite likely it was a cargo cult addition while doint that
for DT-based enumeration.  Drop most likely fake ACPI ID.

Googling for LTERxxxx gives no useful results in regard to DSDT.
Moreover, there is no "LTER" official vendor ID in the registry.
