[PATCH v4 14/18] I2C: OMAP1/OMAP2+: create omap I2C functionality flags for each cpu_... test

[Kevin Hilman]

From: Andy Green <andy at warmcat.com>

These represent the 8 kinds of implementation functionality
that up until now were inferred by the 16 remaining cpu_...()
tests in the omap i2c driver.
