yn386 8770cd2f4d stm32/adc: Make ADCAll.read_channel reject invalid channels.
pyb.ADC(channel) checks whether specified channel is valid or have ADC
capability but pyb.ADCAll().read_channel() does not.

This change adds checking whether specified channel is valid and throw
ValueError if channel is invalid.  This is same as pyb.ADC().
