A new 'p2m_epc' type is added for EPC mapping type. Two wrapper functions
set_epc_p2m_entry and clear_epc_p2m_entry are also added for further use.

Other groups in Intel have been looking to reduce the number of p2m types we have, so we can use more hardware defined bits in the EPT pagetable entries.

If we need a new type then we will certainly add one, but it is not clear why this type is needed.
