pinctrl: meson: amlogic-a4: fix deadlock issue

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: meson: amlogic-a4: fix deadlock issue

Accessing the pinconf-pins sysfs node may deadlock.

pinconf_pins_show() holds pctldev->mutex, and the platform driver
calls pinctrl_find_gpio_range_from_pin(), which tries to acquire
the same mutex again, leading to a deadlock.

Use pinctrl_find_gpio_range_from_pin_nolock() to fix this issue.
