Subject: MIPS: ralink: Remove unused rt*_wdt_reset functions

From: Arnd Bergmann <arnd@arndb.de>

commit 886f9c69fc68f56ddea34d3de51ac1fc2ac8dfbc upstream.

All pointers to these functions were removed, so now they produce
warnings:

arch/mips/ralink/rt305x.c:92:13: error: 'rt305x_wdt_reset' defined but not used [-Werror=unused-function]

This removes the functions. If we need them again, the patch can be
reverted later.
