[PATCH] ARM: mach-mxs: readd just removed select CLKSRC_OF

MXS based apx4devkit doesn't boot with latest Linux v3.15-rc1
because commit ddb902cc34593ecb88c368f6e15db3cf829c56fe removed
"select CLKSRC_OF" from the machine config.

I think commit ddb902cc34593ecb88c368f6e15db3cf829c56fe might break
also other armv4/5 based boards which are using CLKSRC_OF. There is
already patch for MOXA ART SoCs: https://lkml.org/lkml/2014/4/11/308
