Adc isAdcChannelValid helper (#2188) * Guard define argument * ADC: isAdcChannelValid Check for both <= EFI_ADC_NONE and >= EFI_ADC_LAST_CHANNEL Also check for value out of enum range (corrupted settings) * Fix unit tests 2021-01-05 13:02:20 -08:00			`#define adcToVoltsDivided(adc) (5.0f / 4095 * (adc))`
