Replace the non-standard vendor prefix stm and st-micro with st for STMicroelectronics. The drivers do not specify the vendor prefixes since the I2C Core strips them away from the DT provided compatible string. Therefore, changing existing device trees does not have any impact on device detection. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Rob Herring <robh@kernel.org>
