arm: Remove use of board_early_init_r/last_stage_init()

These boards define CONFIG_LAST_STAGE_INIT and CONFIG_BOARD_EARLY_INIT_R
but these options are not available on ARM. Move them into the powerpc
common file instead.

This change affects: km_kirkwood_pci, mgcoge3un, kmnusa, kmcoge5un,
km_kirkwood and portl2.
