i2c-omap: Enable workaround for Errata 1.153 based on
Silicon Errata 1.153 has been fixed on OMAP 3630|4430 with the use of a later version of I2C IP block. The errata impacts OMAP 2420|2430|3430, enable the workaround for these based on I2C IP block revision number instead of OMAP CPU type Signed-off-by: Moiz Sonasath <m-sonasath@ti.com> Signed-off-by: Vikram Pandita <vikram.pandita@ti.com Reviewed-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
