cardem: use USART timeout for waiting time

Browse Source 
the reset/ATR handling has been heavily updated/fixed.
instead of using the timer counter peripheral to handle
the waiting time and corresponding timeout, the USART peripheral
internal timeout mechanism is used.
this is particularly important for the SIMtrace board since the
clock signal is not connected to the timer counter.
thus this change adds card emulation support for SIMtrace boards.

Fi and Di have been properly rename to F and D since the "i"
stands only for an "indicated" value, not the actual value.
this does not change the USB protocol (the variable have just been
renamed).
additional variables store more information about the card
capabilities

NOTE: it has only be tested for the SIMtrace board
