stm: sdioio: remove unused code related to "SD Card detect pin"
.. this probably came from the examples that I studied at the beginning of implementation. The card detection feature is unused. As a "detect pin" is not sent from the shared-bindings, there is no way to get the correct pin anyway. Instead, if code needs to detect the insertion state it can directly use the pin as GPIO in Python code.
