[PATCH v2] i2c: fix missing handling of errata I2C_OMAP3_1P153

Sorry about the bad mails. First time I use git send-email to follow up on a patch, and it seems I need to read up a bit more on it.

Anyway.

This patch is tested on our custom board based on Beagleboard rev C3.

Subject: [PATCH] i2c: fix missing handling of errata I2C_OMAP3_1P153

i2c_prope set the dev->errata flag, but omap_i2c_init cleared the flag again. Move the errata handling to i2c_probe.
