[PATCH v2] pinctrl: qcom: ssbi-gpio: Fix fwspec parsing bug

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

We are parsing SSBI gpios as fourcell fwspecs but they are
twocell. Probably a simple copy-and-paste bug.

Tested on the APQ8060 DragonBoard and after this ethernet
and MMC card detection works again.

ChangeLog v1->v2:
- Renamed function pointer field to .populate_parent_alloc_arg
  as it is named upstream.
