[U-Boot] [PATCH v2 01/19] dm: i2c: Add a dm_ prefix to driver model bus speed functions

Fri Feb 6 05:41:32 CET 2015
As with i2c_read() and i2c_write(), add a dm_ prefix to the driver model
versions of these functions to avoid conflicts.
Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- Use a dm_ prefix for remaining conflicting I2C functions
