mpc85xx: Base emulator support
Prepare for emulator support for mpc85xx parts. Disable DDR training and skip wrlvl_cntl_2 and wrlvl_cntl_3 registers. These two registers improve stability but not supported by emulator. Add CONFIG_FSL_TBCLK_EXTRA_DIV for possible adjustment to time base. Signed-off-by: York Sun <yorksun@freescale.com>
