Fix error reporting on ports/analog BUSIO for PR 10413
- Use existing error messages from locale/circuitpython.pot for most error messages - Replace ConnectionError (networking specific) calls with others (usually RuntimeError) - Remove '\n' from mp error calls (since they add it already) - Remove some redundant validation code that repeats checks done by shared-bindings/common-hal/busio code. e.g. pin validation Signed-off-by: Brandon-Hurst <[email protected]>
