[PATCH -stable] watchdog: mtx1-wdt: fix build failure

[Florian Fainelli <florian@openwrt.org>]

Commit 6d86a0ee (watchdog: mtx1-wdt: request gpio before using it) was
backported from upstream. The patch is using a gpiolib call which is only
available in kernel 2.6.34+. Fix build by using the "old" gpiolib API
instead.
