make the cache_as_ram_auto for init.o to use printk now, 

        printk_debug("linxbios_ram.bin length = %08x\r\n", olen);
        print_debug("linxbios_ram.bin length = "); print_debug_hex32(olen);

there is some space for optimize code for the raminit and ht init in auto

The 8 way system get most benefit from the cache-as-ram solution.
1. with romcc, the compile time may need 5 minutes and can not enable vga
2. win cache as ram and gcc, compile only need 23 seconds. ( the same as
four way and two way), and vga support is already enabled.

the system with multi CK804 as slaves can get some benefits too.
