cpu/x86/mtrr: add x86_setup_mtrrs_with_detect_no_above_4gb()
There's not a function that is the equivalent to x86_setup_mtrrs_with_detect() but not solving for above 4GiB. Provide x86_setup_mtrrs_with_detect_no_above_4gb() which is the equivalent to x86_setup_mtrrs_with_detect() but instructs the MTRR solver to not take into account memory above 4GiB.
