x86: Add an 'mtrr' command to list and adjust MTRRs
It is useful to be able to see the MTRR setup in U-Boot. Add a command to list the state of the variable MTRR registers and allow them to be changed. Update the documentation to list some of the available commands. This does not support fixed MTRRs as yet. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Bin Meng <bmeng.cn@gmail.com>
