powerpc/fsl_soc: improve and simplify get_baudrate
Use of_property_read_u32 instead of the generic of_get_property to simplify the code. In addition move the declaration of fs_baudrate into get_baudrate because it's private to this function. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Scott Wood <oss@buserror.net>
