[PATCH 2/3] thermal: intel: int340x: Add DLVR support for Nova Lake

[Srinivas Pandruvada]

Add support for DLVR (Digital Linear Voltage Regulator) for Nova Lake.
There are no new sysfs attributes or difference in operations compared
to prior generations.

MMIO offset and bit positions are changed. Also no mapping is required
as units are already in MHz.
