thermal: intel: int340x: Capability to map user space to firmware values

To ensure compatibility between user inputs and firmware requirements,
a conversion mechanism is necessary for certain attributes. For instance,
on some platforms, the DLVR frequency must be translated into a predefined
index before being communicated to the firmware. On Lunar Lake platform:
RFI_FREQ_SELECT and RFI_FREQ:
Index 0 corresponds to a DLVR frequency of 2227.2 MHz
Index 1 corresponds to a DLVR frequency of 2140 MHz

Introduce a feature that enables the conversion of values between user
space inputs and firmware-accepted formats. This feature would also
facilitate the reverse process, converting firmware values back into user
friendly display values.

To support this functionality, a model-specific mapping table will be
utilized. When available, this table will provide the necessary
translations between user space values and firmware values, ensuring
seamless communication and accurate settings.
