usbc: add checks for results of TCPC functions

This commit adds checks for results and in case of error, handles it.
The failed initialization of the TCPC can postpone initialization in
case the TCPC needs more time after powering up. Otherwise if other
error happened, the Type-C Layer will be disabled.
Errors in other places of the USB-C stack, like communication errors,
moves the state machine to the error recovery, restarting the
communication with parner.
