[PATCH] nand: gpmi-nand: Fix clock registration

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

On a mx28 board the following error happens since commit 638064e56c 
(mtd: gpmi: change the code for clocks):

gpmi-nand: probe of 8000c000.gpmi-nand failed with error -12

Acquire the clock using "NULL" as it was done previously, so that the driver
can register on mx23/mx28 as well.
