lib: utils/gpio: Fix RV32 compile error for designware GPIO driver

Browse source 
Currently, we see following compile error in the designeware GPIO driver
for RV32 systems:

lib/utils/gpio/fdt_gpio_designware.c:115:20: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  115 |         chip->dr = (void *)addr + (bank * 0xc);
      |                    ^
lib/utils/gpio/fdt_gpio_designware.c:116:21: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  116 |         chip->ext = (void *)addr + (bank * 4) + 0x50;

We fix the above error using an explicit type-cast to 'unsigned long'.
