I got confused by the "GPIO_HIZ" setting, HiZ mean tristated output GPIO, which is not what this is about and something that Ingenic SoCs don't support. Naming that macro e.g. GPIO_PULL_DIS would be much more representative to its meaning. Please rename the macro and remove this check (and the other one below).

Add support for probing the pinctrl-ingenic driver on the X1830 Soc from Ingenic. Signed-off-by: Zhou Yanjie <zhouyanjie@zoho.com> --- Notes: v2: New patch. v2->v3: Add pinctrl drivers for the PWM of X1830. v3->v4: 1.Use local variables to streamline code. 2.Prevents processors older than X1830 from being configured in HiZ mode. v4->v5: Fix compile-time warnings.
