Modify the RT5640 driver to parse platform data from device tree. Write
a DT binding document to describe those properties.
Slight re-ordering of rt5640_i2c_probe() to better fit the DT parsing.
Since ldo1_en is optional, guard usage of it with gpio_is_valid(), rather
than open-coding an if (gpio) check.
