mainboard/google/fatcat: Add TODO for Fast VMode settings

We've added a TODO comment to the device tree configuration file to
remind us to set the appropriate values for 'enable_fast_vmode',
'cep_enable', and 'fast_vmode_i_trip' chipset fields.

These settings are critical for achieving optimal power performance and
efficiency in the Panther Lake U series.

Currently, no actual values have been set as further investigation and
testing are required to determine the most effective configurations. The
TODO comments serve as a placeholder for these values and a reminder to
revisit this as part of our ongoing development efforts of the Fatcat
project.

Further commits will include the fine-tuning of these parameters after
extensive testing to ensure they meet our performance and power criteria
without compromising system stability.
