I think this can break boards with MX3 where the MC13783 is used, and
where MC13892 is not set.

At the moment, MC34704 is the one that requires a short lenght. Maybe it
is better to set 3 as default:

#if defined(CONFIG_PMIC_FSL_MC34704)
#define FSL_PMIC_I2C_LENGTH	1
#else
#define FSL_PMIC_I2C_LENGTH	3
#endif
