We don't have audio support in U-Boot, but we do have boot menus. Add an
option to re-map the volume and power buttons to up/down/enter so that
in situations where these are the only available buttons (such as on
mobile phones) it's still possible to navigate menus built in U-Boot or
an external EFI app like GRUB or systemd-boot.

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.

Qualcomm PMICs include a "pon" function which handles two buttons, the
power button and "resin" button (usually volume down). Introduce a new
driver following upstream Linux DT to enable these and map them to Enter
and Down respectively to enable use in boot menus.

The gpio-button driver depends on DM_GPIO, add it to Kconfig to avoid
build errors.

Add a simple Analog to Digital Converter device based button driver. This
driver binds to the 'adc-keys' device tree node.
