BOOT: Add RAW ramdisk support to bootz

Browse Source 
This patch allows loading RAW ramdisk via bootz command. The raw ramdisk is
loaded only in case it's size is specified:

  bootz <kernel addr> <ramdisk addr>:<ramdisk size> <fdt addr>

For example:

  bootz 0x42000000 0x43000000:0x12345 0x44000000
