Drop the USE_PRINTK_IN_CAR option. It's a bogus decision to make for any user /
board porter: printk should always be available in CAR mode.
Also drop CONFIG_USE_INIT, it's only been selected on one ASROCK board
but it's not been used there. Very odd.
There is one usage of CONFIG_USE_INIT which was always off in
src/cpu/intel/car/cache_as_ram.inc and we have to figure out what to do with
those few lines.
