drivers/ch347: fix SWD log messages

Browse Source 
Remove annoying and not too informative error message `ack != SWD_ACK_OK`.
Fix copy&paste error in message `SWD Read data parity mismatch` logged
in case of a write returning bad ack.
Raise log level of read/write descriptive message to DEBUG when reg
read/writes returns bad ack.
