The pmic_init() function has the I2C or SPI bus number that is connected to the PMIC. Instead of passing I2C_PMIC, explicitly pass the I2C bus number via I2C_x definition. The motivation for doing this is to avoid people just doing a copy and paste of I2C_PMIC into their board file when another I2C bus is actually used to interface to their PMIC. This also makes more obvious which is the I2C bus connected to the PMIC, without having to search in the source code for the meaning of the 'I2C_PMIC' number.
