PATCH 1/1 MIMC200: tidy GCLK init code

Change the MIMC200 startup code to use the built-in (rather than hard-coded) funtions for setting up gclk outputs.

We'll also move the code to the new, more-appropriate board_postclk_init() routine.

I think you will have to rebase this patch. It does not apply any more.

Best regards,

Wolfgang Denk
