From: heyunlei <heyun...@huawei.com>
On our arm platform, some modules (e.g. I2C bus driver) use the
pinctrl-single driver to configure the SoC pin, but pinctrl-single
driver uses module_init time, that makes some modules initialize ahead
the pinctrl-single and fail to register.
This patch changes the initialization priority of pinctrl-single from
module_init time to arch_initcall time.
