stm32l1: adc: use v1-m shared code. 

Drops all the l1 copies of this code, and automatically gains all the
following apis that weren't even available before:

void adc_set_clk_prescale(uint32_t prescaler);
void adc_set_resolution(uint32_t adc, uint32_t resolution);
void adc_enable_overrun_interrupt(uint32_t adc);
void adc_disable_overrun_interrupt(uint32_t adc);
bool adc_get_overrun_flag(uint32_t adc);
void adc_clear_overrun_flag(uint32_t adc);
bool adc_awd(uint32_t adc);
void adc_eoc_after_each(uint32_t adc);
void adc_eoc_after_group(uint32_t adc);
void adc_set_dma_continue(uint32_t adc);
void adc_set_dma_terminate(uint32_t adc);
