README.hardware: update flashing instructions for MPC8315
Using 1000000 memory address for kernel and a00000 for dtb can cause kernel image to overwrite dtb when uncompressing and u-boot crashing with: ERROR: image is not a fdt - must RESET the board to recover. Updated flashing instructions for the board to use addresses 1000000 and 2000000 to avoid this error. Got rid of resetting loadaddr and ftdaddr u-boot variables.
