This commit makes power limit helper functions accessible during
romstage by updating the Makefile to include `power_limit.c` for both
ramstage and romstage.
It also modifies a preprocessor directive to ensure
`variant_update_cpu_power_limits()` is not compiled in romstage as it is
only intended for late-in-the-boot usage and will not compile properly
in romstage.
This change enables power management configuration identification early
in the boot process, allowing for better control over power settings at
this stage.
TEST=Successfully compile the Fatcat board target.
