Introduce FSL_PMIC_I2C_LENGTH to configure the number of bytes that are used to communicate with the PMIC via I2C.
Instead of hardcoding the value, pass the number via a configurable option per PMIC type.
This will be useful for adding support for PMIC MC34704 from Freescale, which uses only one byte in its I2C protocol.
Signed-off-by: Fabio Estevam fabio.estevam@freescale.com --- Changes since v2: - Do not pass FSL_PMIC_I2C_LENGTH in the board file
