[ARM] 2980/1: Fix L7200 core.c compile

Patch from Deepak Saxena

This patch fixes L7200 so that it builds in 2.6.latest. I do not
have the hardware so don't know if it actually still works, but
the changes are fairly trivial. I am not even sure if anyone
still maintains, uses, or cares about this machine type.
