ARC: Setup Vector Table Base in early boot
commit 05b016ecf5e7a8c24409d8e9effb5d2ec9107708 upstream.
Otherwise early boot exceptions such as instructions errors due to
configuration mismatch between kernel and hardware go off to la-la land,
as opposed to hitting the handler and panic()'ing properly.
