[PATCH v5 2/4] arc: Add inclusion of "gdbarch.h" in "arc-tdep.h"

[Shahab Vahedi]

From: Shahab Vahedi <shahab@synopsys.com>

The "arc-tdep.h" makes use of definitions in "gdbarch.h", but it
does not include it explicitly.  I have piggy backed this fix
in another commit [1], but I was asked to do it separately [2].
