[PATCH] ata: pata_imx: Convert to clk_prepare_enable/clk_disable_unprepare

[PATCH] ata: pata_imx: Convert to clk_prepare_enable/clk_disable_unprepare

[Fabio Estevam]

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

With the new i.mx clock framework, we need to use clk_prepare_enable/clk_disable_unprepare.
