Hi Tom,

These changes adds support for reading the ADC key on the Khadas VIM3 & VIM3L, in the same time it adds plumbing for ADC keys and a test for sandbox. This time with s/treshold/threshold/.

The CI job is at https://gitlab.denx.de/u-boot/custodians/u-boot-amlogic/pipelines/6480

Thanks, Neil
