stm32f0: make ADC watchdog feature modular
The ADC watchdog is about 2/3 of the ADC code size and it is not
optimized out when not used because adc_read_channel() needs to
stop/restart the watchdog if somebody is using it.
The feature is enabled by default to keep the current behavior on
STM32F0 platform, and it is turned off on samus_pd :
This is saving 448 bytes of flash (and 8 bytes of RAM).

BRANCH=none
BUG=none
TEST=make buildall and check the firmware size before and after.
when CONFIG_ADC_WATCHDOG is disabled, adc_enable_watchdog() is not
compiled if there is any user the build will fail.
