AFAICT, the value 0 for multi-mode type 4 is specified to be reserved.
If this happens at boot time, then maybe it really tells us that the
current state is not known at the time similar to what appears to be
the case for other modes.

Sounds like the best solution is to just assume that a value of 0x0
always means the state is unknown and assume we are in laptop mode.

Simply adding TP_ACPI_MULTI_MODE_UNKNOWN to the lists of valid modes
should fix the warning.
