Most bsp.h: Switch to LIBBSP_@CPU@_@BSP_FAMILY@_H for guard

This was done by the following script run from libbsp:

find * -name bsp.h | xargs -e grep -l "#ifndef.*_BSP_H" | while read b
do
  echo $b
  cpu=`echo $b | cut -d'/' -f1 | tr '[:lower:]' '[:upper:]' `
  bsp=`echo $b | cut -d'/' -f2 | tr '[:lower:]' '[:upper:]' `
  g="LIBBSP_${cpu}_${bsp}_BSP_H"
  # echo $g
  sed -e "s/ifndef _BSP_H/ifndef ${g}/" \
      -e "s/define _BSP_H/define ${g}/" \
  -i $b

done
