thermal: intel: int340x: processor: Move RAPL defaults to MMIO driver

Browse Source 
Previously, the MMIO and MSR RAPL interfaces shared the same set of
RAPL defaults provided by common code. However, unlike the MSR
interface, the MMIO RAPL interface does not require CPU-specific
variations in its default handling. Keeping the RAPL defaults in
the RAPL common driver therefore provides no additional benefit.

Move the MMIO defaults into the MMIO interface driver. This change
includes the following updates:

  * Introduce a MMIO-local rapl_defaults instance with the appropriate
    default callbacks.
  * Assign the MMIO-specific rapl_defaults to priv->defaults during
    MMIO driver initialization.

No functional changes are expected.
