boards: arduino: uno_r4: enable all ioports needed by the arduino header

The arduino Uno R4 has only ioport1 enabled in the dts. The arduino
header however uses ioport0,1,3 [minima variant] and ioport 0,1,3,4
[wifi variant]. This causes a build failure for some of the pins.

This change makes sure than an application can use any arduino pins.
