gpio: dw: Add ngpios DT-property support
Starting with Linux commit 7569486d79ae ("gpio: dwapb: Add ngpios
DT-property support") the "snps,nr-gpios" property was marked
as deprecated.
And since all newly added dw-apb-gpio nodes are described using generic
"ngpios" property, it's time to add support for it.
