MFC r198319:
On error, freeze device queue, to allow periph driver to do proper recovery.
Freeze SIM queue only in some cases, when it is needed to protect SIM.
Implement better command timeout detection logic for non-queued commands.
This fixes false positives when command with short timeout waiting for the
long one. For example, when hald tastes CD during burning process.
Read and clear SERR register on interrupt.
