soc/intel/elkhartlake/systemagent: Disable RAPL based on Kconfig

This patch provides the possibility for EHL based boards to disable
RAPL settings via SOC_INTEL_DISABLE_POWER_LIMITS config switch.

On Elkhart Lake the way via setting relevant MSR bits does not work.
Therefore the way via MCHBAR is choosen.

Test:
Check MCHBAR mapped registers (MCH_PKG_POWER_LIMIT) on mc_ehl1.
