The WM8782 can safely support rates higher than 48kHz by changing the value of the FSAMPEN pin.
Allow specifying the FSAMPEN pin value in the device tree.

+Optional properties:

What's the default if the property is not present?
Example:
wm8782: stereo-adc { compatible = "wlf,wm8782"; Vdda-supply = <&vdda_supply>; Vdd-supply = <&vdd_supply>;
- wlf,fsampen = <2>; /* 192KHz */
