[U-Boot] [PATCH v2 3/5] pmic_fsl: Introduce CONFIG_SYS_FSL_PMIC_I2C_LENGTH

From: Fabio Estevam <fabio.estevam at freescale.com>
Introduce CONFIG_SYS_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 config option.
This will be useful for adding support for PMIC MC34704 from Freescale, which
uses only one byte in its I2C protocol.
