What makes you say that these properties are wrong?  Are you sure that
this isn't just some other systems using different ACPI properties given
the poor standardization for ACPI?  Your new ones look like they're DT
properties pulled into ACPI while the existing ones look more idiomatic
for ACPI.  It'd be fine to add your new DT style properties but this
might break existing systems.
