Subject: [PATCH v2] pinctrl: bcm: bcm6362: fix warning

The current implementation of bcm6362_set_gpio() produces the following
warning on x86_64:
drivers/pinctrl/bcm/pinctrl-bcm6362.c: In function 'bcm6362_set_gpio':
drivers/pinctrl/bcm/pinctrl-bcm6362.c:503:8: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  503 |        (uint32_t) desc->drv_data, 0);
      |        ^

Modify the code to make it similar to bcm63268_set_gpio() in order to fix
the warning.
