Kévin Redon 07fda1e706 card_emu: use edge-triggered VCC ADC logic ...

Before this patch, we used to st ci->vcc_active depending on the
instantaneous ADC reading of VCC.  Is it > .5v, we claim VCC is active,
and if it's below, VCC is inactive.

With this patch we move to an edge triggered approach: Only change
ci->vcc_active if the previous reading was different from the current
reading.

FIXME: why?
