arch/x86: Utilize additional MTRRs in postcar_frame_add_mtrr

In the current implementation of postcar_frame_add_mtrr,
    if provided size is bigger than the base address alignment,
    the alignment is considered as size and covered by the MTRRs
    ignoring the specified size.
    In this case the callee has to make sure that the provided
    size should be smaller or equal to the base address alignment
    boundary.

To simplify this, utilize additonal MTRRs to cover the entire
    size specified. We reuse the code from cpu/x86/mtrr/mtrr.c.
