i2c-omap: Enable workaround for Errata 1.153 based on

Moiz Sonasath · Ben Dooks · commit 61149787d65b · 2009-08-20T22:27:58.000+01:00
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
