mb/google/rex: Simplify power limit configuration usage
This patch removes the deprecated PL_PERFORMANCE and PL_BASELINE
configurations, relying instead on the refactored power limit flow.
This flow allows for seamless overrides by the baseboard and/or by
the variant board, if necessary.
Specifically, this patch:
- Removes PL_PERFORMANCE and PL_BASELINE configuration options from
mainboard.c in the google/rex directory.
- Relies on the baseboard_devtree_update() function, which is
implemented by the respective baseboard, to handle power limit
configuration.
- Leverages the variant_devtree_update() function, which is a
__weak implementation, to allow overrides by the variant directory.
This simplification improves code readability and maintainability while
maintaining the flexibility to handle power limit configurations as
needed.
