gpio: generic: factor into gpio_chip struct
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make things simpler: include the fields directly into <linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix some of the member variables with bgpio_* and add proper kerneldoc while we're at it. Modify all users to handle the change and use a struct gpio_chip directly. And while we're at it: replace all container_of() dereferencing by gpiochip_get_data() and registering the gpio_chip with gpiochip_add_data().
