README.hardware: remove u-boot flashing instructions for mpc8315e-rdb
Upgrading u-boot is apparently not necessary with current board revisions,
and these instructions may not work properly anyway (our toolchain seems not
to be able to compile u-boot in the way described), and given that they are
potentially risky they should be removed.
