bcma: Use the proper gpio include

The <linux/bcma/bcma_driver_chipcommon.h> is including the legacy
header <linux/gpio.h> to obtain struct gpio_chip. Instead, include
<linux/gpio/driver.h> where this struct is defined.

It turns out that the brcm80211 brcmsmac depends on this to
bring in the symbol gpio_is_valid().

The driver looks up the BCMA parent GPIO driver and checks that
this succeeds, but then it goes on to use the deprecated GPIO
call gpio_is_valid() to check the consistency of the .base
member of the BCMA GPIO struct. The whole check can be dropped
because the bcma_gpio is initialized in the declarations:

  struct gpio_chip *bcma_gpio = &cc_drv->gpio;

And this can never be NULL.
