mpc83xx: add OF_FLAT_TREE bits to 83xx boards

add ft_pci_setup, OF_CPU, OF_SOC, OF_TBCLK, and
STDOUT_PATH configuration bits to mpc8349emds,
mpc8349itx, and mpc8360emds board code.

redo environment to use bootm with the fdtaddr
for booting ARCH=powerpc kernels by default,
and provide default fdtaddr values.
