make adc2uv common
when building the trace app for the simtrace board gcc was outputing
the following error:
libboard/common/source/boardver_adc.c:20:17: warning: 'adc2uv' defined but not used [-Wunused-function]
static uint32_t adc2uv(uint16_t adc)
adc2uv is used by qmod, and defined in two places:
in boardver_adc.c and mode_cardemu.c.
this change will have adc2uv only defined in boardver_adc.c and make
available in the header to be used by mode_cardemu.c.
