MCP230xx: Prevent inadvertent pinmode change 

We've added support for sensor29 pin,0/1 for OFF/ON but the current code would allow the pinmode to be changed without specifying a default state e.g. sensor29 pin,3 would cause the pinmode to be changed to input even if it was previously configured for output (pinmode 5/6)

This change prevents these instances by enforcing the configuration rules as outlined in the wiki e.g.

sensor29 pin,pinmode,pullup/default state (if used for output)
