[PATCH 1/2] mtd: rawnand: gpmi: Remove explicit default gpmi clock setting for i.MX6

[Christian Eggers]

From: Stefan Riedmueller <s.riedmueller@xxxxxxxxx>

There is no need to explicitly set the default gpmi clock rate during
boot for the i.MX 6 since this is done during nand_detect anyway.

@stable: This patch fixes a bug because this (superfluous) call to
         clk_set_rate() misses the required clock gating. The resulting
         clock glitches can prevent the system from booting.

Changelog:

RFC --> v1
