[ARM] 4292/1: ns9xxx: Make REGGET consistant with REGSET

This implies that REGGET gets a new parameter "var" to allow to hold the actual
register value in a variable.

Moreover REGGET was broken because it used "field" instead of
"reg ## _ ## field" which proves that there are no callers to fix :-)
