arm: spear: enable GPIO3 and 4 clocks when the GPIO controller driver is built

Browse Source 
There are multiple GPIOs that can be used with the same driver depending
on the CONFIG_GPIO_BASE defined in the controller driver.

GPIO3 and 4 require a clock to be enabled so let's enable them when the
driver is built.
