mainboard/google/fatcat: Update SoC to Panther Lake

This commit updates the fatcat mainboard to use the Panther Lake SoC
instead of Meteor Lake.

The changes include:

- Selecting the `SOC_INTEL_PANTHERLAKE_U_H` config option.
- Updating the `mainboard_update_soc_chip_config()` function to use the
  `soc_intel_pantherlake_config` struct.
- Updating the devicetree to use the `soc/intel/pantherlake` chip.
- Updating variant header files to reflect the SoC change.

This update enables support for the Panther Lake SoC and its
features on the fatcat mainboard.

BUG=b:347669091
