Subject: [PATCH] ARM: remove ARM710 specific assembler code

Support for ARM710 CPUs was removed in v3.5. But a few lines of ARM710
specific assembler code were left in the tree. Remove these too.

Signed-off-by: Paul Bolle <pebolle@...cali.nl>

This minor cleanup was suggested by Arnd. This patch is mostly
guesswork, as I already told Arnd, since I have never touched ARM
assembler before (as far as I can remember). Untested too! And this does
need testing.
