Add devicetree-bindings for the dmic, jack-detect source and overcurrent-
detect threshold settings.
The dmic bindings mirror the existing bindings for the rt5645.
The jd-src and ovcd bindings mirror the existing bindings for the rt5651.

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.
