Daniel Leung 32d42f313e gpio: pcal9535a: use polling I2C write instead ... The polling I2C write function guarantees the write operation is completed. Given that the initialization routine goes through I2C write consecutively, we want to make sure each write has been committed. Also adds code to configure the I2C controller before transfer.
