mb/google/rex/var/baseboard/ovis: Support CPU power limits per variant

There is no direct way to override CPU default power_limits for
different SKUs.

This CL add structure variant_get_soc_power_limit_config() for
variants to define and configure the values of soc_power_limits_config
for current CPU SKU.

Variants can override these values i.e. pl1, pl2, psyspl2
in variant_devtree_update().
