[PATCH] clk: gpio: Fix buggy merge

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@nxp.com>

Clock maintainer mis-merged Russell King's commit 7ed88aa2efa54
("clk: fix clk-gpio.c with optional clock= DT property")
causing the gpio-gate-clock not to be registered.

Adjust the code, so that it looks like Russell's original submission.

With this fix in place, Wifi chip can be successfully probed on a
imx6q-cubox-i.
