DaVinci: fix GPIO breakage after v4.19

Browse Source 
This set of changes is needed to fix the broken GPIO support
 for DaVinci boards in legacy mode after certain changes made to the
 GPIO driver in 4.19, namely: commits 587f7a694f ("gpio: davinci: Use
 dev name for label and automatic base selection") and eb3744a2dd
 ("gpio: davinci: Do not assume continuous IRQ numbering").
