Subject: 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.

-\subsection{car + CONFIG\_USE\_PRINTK\_IN\_CAR images}
-When CONFIG\_USE\_PRINTK\_IN\_CAR is set, the CAR code can use printk instead of the primitive print functions. This config variable is used in one of two ways. If CONFIG\_USE\_INIT is 0, then different .c files just include other .c files, as in console.c:
-\begin{verbatim}
-#if CONFIG_USE_PRINTK_IN_CAR == 0
-static void __console_tx_byte(unsigned char byte)
