initialize VCC, RST, and VCC with actual values

Browse Source 
previously the card RST, VCC, and CLK signal states have been initialized with
default values corresponding to an inactive reader.
this worked fine for actual inactive readers since the default values match
and would be updated when the signal changes (edge detection).
but if the reader is in another state, card activation detection could fail.
this is fixed since the actual signal values are now used during initialisation.

at the same time I changed the variable type from uint8_t to boolean since they
have only two possible states, and understanding the actual state when coding
is simpler (no need to check which integer corresponds to which state).

this change has been successfully tested on the 2 slots of OWHW board.
