Subject: [BUG] pinctrl: sunxi: sunxi-pinctrl fail to load with
 CONFIG_DEBUG_TEST_DRIVER_REMOVE

Hello

With CONFIG_DEBUG_TEST_DRIVER_REMOVE=y pinctrl-sunxi fail to load on the second try.

[    3.900061] sun8i-h3-pinctrl 1c20800.pinctrl: initialized sunXi PIO driver
[    3.916251] gpio gpiochip1: GPIO integer space overlap, cannot add chip
[    3.923016] gpiochip_add_data: GPIOs 0..223 (1c20800.pinctrl) failed to register
[    3.931099] sun8i-h3-pinctrl: probe of 1c20800.pinctrl failed with error -16
[    3.944709] sun8i-h3-r-pinctrl 1f02c00.pinctrl: initialized sunXi PIO driver
[    3.960796] gpio gpiochip2: GPIO integer space overlap, cannot add chip
[    3.967594] gpiochip_add_data: GPIOs 352..383 (1f02c00.pinctrl) failed to register
[    3.975633] sun8i-h3-r-pinctrl: probe of 1f02c00.pinctrl failed with error -16

Without it, all subsequent drivers fail to load.
Tested on Orange PI PC board.
