Subject: [PATCH] i2c: i2c-elektor: Allow building on SMP kernels

It the past the i2c-elektor driver has been broken on SMP, as it seems
there has since been some fixes/cleanup work to get rid of cli/sti and
rely on spinlocks instead (as pointed out by Wolfram Sang). Tested this
driver on SMP kernel on Alpha/UP2000+ for a few days without any problems.
