[PATCH 2/2] pinctrl: canaan: k230: Fix order of DT parse and pinctrl register

[Ze Huang]

Move DT parse before pinctrl register. This ensures that device tree
parsing is done before calling devm_pinctrl_register() to prevent using
uninitialized pin resources.

Fixes: 545887eab6f6 ("pinctrl: canaan: Add support for k230 SoC")
