[PATCH 3 08/18] I2C: OMAP2+: use platform_data ip revision to select register map

[Andy Green]

Change the register map names to reflect the IP revision they
are representing, and use the platform_data IP revision index
to select between them at init time.

Eliminates 1 of 17 cpu_...() calls in the driver.
