In case of initrd/initramfs /dev/console might not exist that early
as devtmpfs is mounted a bit later by /init process so disable this
check in that case.

Handle U-boot arguments paranoidly:
* don't allow to pass unknown tag.
* try to use external device tree blob only if corresponding tag
(TAG_DTB) is set.
* don't check: uboot_tag if kernel build with no ARC_UBOOT_SUPPORT.
While I'm at it refactor U-boot arguments handling code.

In case of devboards we really often disable bootloader and load
Linux image in memory via JTAG. In case of using kernel with
CONFIG_ARC_UBOOT_SUPPORT enabled we may crash as we will try to
interpret some junk in a registers as a pointers to bootargs/etc
which aren't set by anyone in case of JTAG u
