Minor cleanup to ARM926 debug entry:

 - don't needlessly export this function
 - handle "case 0" debug method-of-entry better (silent by default)

The "case 0" is a valid debug entry mode so it doesn't deserve the
warning int now gets.  But it probably means that OpenOCD confused
itself somehow; or that it confused the ARM9EJS target.
