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.
Other than on previouse SOCs this needs to be done in an MCHBAR mapped
register rather than via MSR on Elkhart Lake.

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