[PATCH] pinctrl: devicetree.c: remove orphan pinctrl_dt_has_hogs()

[Rasmus Villemoes <linux@rasmusvillemoes.dk>]

The helper pinctrl_dt_has_hogs() was introduced in
99e4f67508e1 (pinctrl: core: Use delayed work for hogs), but the sole
use then got removed shortly after in 950b0d91dc10 (pinctrl: core: Fix
regression caused by delayed work for hogs).
