patches for SIM in the firmware

Hello guys, attached is a patch that fixes a few issues regarding SIM reader in Motorola phones (tested on C123), description: if there’s a lot of reading from SIM it happens a FIFO gets full, IMHO the right way is to read until the FIFO is empty (while-loop added) FETCH APDU has to be handled in the same way as GET RESPONSE (added) once REG_SIM_IT_SIM_NATR is triggered it should set the rxDoneFlag to 1 because otherwise there’s trouble recognising NO SIM state on L1 if SIM isn’t present in calypso_sim_powerup() and calypso_sim_reset() should set state to IDLE and put sim_len to 0 because if you do powerdown/powerup the state machine gets messed up unsetting CONFBYPASS should make the CONFSVCCLEV and CONFSRSTLEV irrelevant but it doesn’t, calypso_sim_powerdown() fixed based on calypso spec both calypso_sim_powerup() and calypso_sim_powerup() now return ATR as it should be when you poweron/reset the card some minor debug messages fixed to keep all the messages consistent Patch is apply-able on the current master. Cheers! Lukas
