Subject: [PATCH] arm: omap2: remove obsolete config OMAP3_SDRC_AC_TIMING

Commit d42f265a5d7a ("ARM: OMAP3: clock: remove un-used core dpll
re-program code") removes arch/arm/mach-omap2/sram34xx.S, which
implemented the effect of the config OMAP3_SDRC_AC_TIMING. Since then, the
OMAP3_SDRC_AC_TIMING config was hanging around without effect.

Remove this obsolete config.
