drivers/gpio: stm32: Use gpio device as gpio_stm32_configure arg

Browse source 
Now that pinmux driver holds a table of GPIO device pointers,
use gpio device as the single source of trust for gpio_base
and remove use of port_base and related code.
This way, gpio_stm32_configure could directly take gpio device
pointer as argument.
