Unfortunately, DT cannot do a binding with the ACPI names. Similarly, ACPI
cannot do a binding with the DT name. 

The structure of binding name is also subject to different kind of rules
for DT and ACPI.

This driver supports both device tree and ACPI. That's why, two different
names are required.
