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.
