soc/intel/*: Move prmrr_core_configure
Move prmrr_core_configure before clearing MCEs. This is required for the following patch in order to update microcode after PRMRR has been configured, but before MCEs have been cleared. According to Document 565432 this should be no issue in regards to SGX activation.
