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.

This fixes write access to PMIC registers, the bug was
introduced partly in commit 64aac65099 and in commit c9fe76dd91.
It was tested on an i.mx31 with a mc13783.
