MIPS: Loongson64: Rename CPU TYPES
CPU_LOONGSON2 -> CPU_LOONGSON2EF
CPU_LOONGSON3 -> CPU_LOONGSON64

As newer loongson-2 products (2G/2H/2K1000) can share kernel
implementation with loongson-3 while 2E/2F are less similar with
other LOONGSON64 products.

a4e5db831a gpio: loongson: Use BIT() macros
This switches the Loongson driver over to using the bitops BIT()
macros and drops some local variables and make the code easier
to read (in my opinion).

70e703e741 gpio: loongson: Create a dynamic platform device
It is pretty helpful to create some kind of device for backing the
GPIO chips, especially when preparing the driver for using
GENERIC_GPIO, so let's create a simple platform device and a simple
platform device driver and create the gpiochip in the .probe() routine
for the device driver. Keep all at the core initcall so the behaviour
is the same as before.

f105edf700 gpio: loongson: Use right include
The driver includes <linux/gpio.h> which is wrong, rely on
<linux/gpio/driver.h> and remove to call to gpio_set_value() in
favor of calling the internal function. Move functions around to
avoid forward declarations.

4eab22e748 gpio: convert remaining users to gpiochip_add_data()
For completion, sweep the floor from all gpiochip_add() usage so
we can remove that function and get rid of the function wrapper
gpiochip_add().
