thermal: intel: int340x: Add DLVR support for Lunar Lake
Add support for DLVR (Digital Linear Voltage Regulator) for Lunar Lake.
There are no new sysfs attributes or difference in operation compared
to prior generations.
MMIO offset and bit positions are changed compared to Meteor Lake
processors. Also for two attributes dlvr_frequency_mhz and
dlvr_frequency_select, the value presented or accepted by the firmware
is not raw frequency value but an index.
For example:
RFI_FREQ_SELECT and RFI_FREQ
: 0 DLVR freq point 2227.2 MHz
: 1 DLVR freq point 2140 MHz
Hence create a mapping table for Lunar Lake to map user space values
to the firmware accepted values.
