USB: io_ti: FIrst cut at a big clean up

Sort out the insane naming like "OperationalFirmwareVersion" which seems
	designed to cause formatting problems and RSI
Merge various common code together
Clean up the pointlessly complex and spread about MCR handling

This is really just the low hanging fruit.

Needs lots of testing before it goes upstream so testers and reports
appreciated
