mpc83xx: Add support for MPC8349 esd caddy2

The caddy2 is a variant of the already supported vme8349. So we just
add the differences to this board port. To better support those two
boards we switched from fixed SDRAM configuration to usage of
spd_sdram(). This is done by providing a board specific SPD EEPROM
routine with different values for both boards.

changed to use mkconfig -t option instead, plus misc codingstyle fixes.
