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.
