Subject: [PATCH] i2c-omap: Fix build breaking typo in cpu_is_omap_2430

Commit 84bf2c86

 introduced a typo, it should be cpu_is_omap2430
instead. The typo was probably caused by a mismerge.

Without this patch all omaps fail to build with:
error: implicit declaration of function 'cpu_is_omap_2430'
