[nvptx] Use no,yes for attribute predicable

The documentation states about the predicable instruction attribute:
...
This attribute must be a boolean (i.e. have exactly two elements in its
list-of-values), with the possible values being no and yes.
...

The nvptx port has instead:
...
(define_attr "predicable" "false,true"
  (const_string "true"))
...

Fix this by updating to:
...
(define_attr "predicable" "no,yes"
  (const_string "yes"))
...

Tested on nvptx.
