gpio: s5p: call: dev_get_addr() instead of fdtdec_get_addr()
After rework in lib/fdtdec.c, the function fdtdec_get_addr()
doesn't work for nodes with #size-cells property set to 0.
To get GPIO's 'reg' property, the code should use one of:
fdtdec_get_addr_size_auto_no/parent() function.
Fortunately dm core provides a function to get the property.
This commit reworks function gpio_exynos_bind(), to properly
use dev_get_addr() for GPIO device.
This prevents setting a wrong base register for Exynos GPIOs.
Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).
