[U-Boot] [PATCH] powerpc/85xx: Change CS timing parameters before changing CS properties on IFC

[Kumar Gala <galak@kernel.crashing.org>]

From: Dipen Dudhat <Dipen.Dudhat@freescale.com>

To make sure that machine change operation work successfully, change
timing parameters first before changing machine for chip select on IFC.
