The BUTTON_ADC symbol guards the compilation of button-adc driver whose name very well makes it explicit that it requires ADC support to be enabled. Fix build issue of button-adc driver when ADC support isn't enabled by making sure it cannot be built without ADC support.

Many boards have buttons which can be used to change behaviour (reset, ...).
|
|
U-Boot provides a uclass API to implement this feature. Button drivers
|
|
can provide access to board-specific buttons. Use of the device tree
|
|
for configuration is encouraged.

Enable support for the power and "resin" (usually volume down) buttons
|

on Qualcomm SoCs. These will be configured as the Enter and Down keys
|
|
respectively, allowing navigation of bootmenu with buttons on device.
