Subject: [PATCH v1 1/1] iio: imu: kmx61: Drop most likely fake ACPI ID

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 KMX61021L gives no useful results in regard to DSDT.
Moreover, the official vendor ID in the registry for Kionix is KIOX.
