Uwe Poeche d2d9021543 intel/common/block: move RAPL disabling to common code
This patch brings the feature of disabling RAPL to common code. It
replaces the current solution for APL and EHL.
For special case if RAPL disabling is only working via changes in MCHBAR
a new config switch was introduced.

Test: Boot mc_apl4/5 with this patch and ensure that the
relevant bits in MSR 0x610 are the same as before the
patch.
