dt-bindings: gpio: dwapb: Add ngpios property support

Browse source 
It's redundant to have a vendor-specific property describing a number of
GPIOS while there is a generic one. Let's mark the former one as
deprecated and define the "ngpios" property supported with constraints
of being within [1; 32] range.
