it83xx/adc: enabled GPIO alternate mode by default for pin into gpio.inc marked as MODULE_ADC
In the ADC initialization function, we should use the function
of gpio_config_module to set alternate function and declare
corresponding alternate function pins in gpio.inc. So we are
able to enable extra flag if needed.
BUG=none
BRANCH=none
TEST=testing the alternate function pins are normal
on the board of it83xx_evb, it8xxx2_evb, it8xxx2_pdevb
and reef_it8320.
