pinctrl/nomadik: allow to support several ranges per GPIO bank
With DB8500 the number of GPIO chips = number GPIO bank =
number of GPIO ranges.
With DB8540, a new GPIO range configuration is used, some GPIO
banks can have several GPIO ranges.
For example, DB8540 GPIO bank0 (GPIO0 to GPIO32) have 2 GPIO
ranges:
- GPIO0 to GPIO17 : routed
- GPIO18 to GPIO21 : hole
- GPIO22 to GPIO28 : routed
- GPIO29 to GPIO32 : hole
Previously, during nmk_pinctrl_probe(), all GPIO ranges were
parsed, as GPIO ranges are larger than the number of GPIO chips,
a warning occurs. This commit allows each bank to have several
GPIO ranges.
