pmic:i2c: Add I2C sensor byte order (big/little) to PMIC framework
Since the pmic_reg_read is the u32 value, the order in which bytes
are placed to form u32 value is important.
Support for big and little sensor endianess is added.
Moreover calls to [leXX|beXX]_to_cpu have been added to support
little and big endian SoCs.
