Now that we support device tree GPIO bindings directly in the driver model
GPIO uclass we can remove these functions.

This deals with the polarity bit. It also changes the GPIO devices so that
the correct device tree node is linked to each one. This allows us to use
the new uclass phandle functionality to implement a proper GPIO binding.

At present U-Boot sort-of supports the standard way of reading GPIOs from
device tree nodes, but the support is incomplete, a bit clunky and only
works for GPIO bindings where #gpio-cells is 2.

Add new functions to request GPIOs, taking full account of the device
tree binding. These permit requesting a GPIO with a simple call like:

   gpio_request_by_name(dev, "cd-gpios", 0, &desc, GPIOD_IS_IN);

This will request the GPIO, looking at the device's node which might be
this, for example:

   cd-gpios = <&gpio TEGRA_GPIO(B, 3) GPIO_ACTIVE_LOW>;

The GPIO will be set to input mode in this case and polarity will be
honoured by the GPIO calls.

It is also possible to request and free a list of GPIOs.

Only the GPIO driver knows about the full GPIO device tree binding used by
a device. Add a method to allow the driver to provide this information to the
uclass, including the GPIO offset within the device and flags such as the
polarity.

So far driver model's GPIO uclass just implements the existing GPIO API.
This has some limitations:

- it requires manual device tree munging to support GPIOs in device tree
    (fdtdec_get_gpio() and friends)
- it does not understand polarity
- it is somewhat slower since we must scan for the GPIO device each time
- Global GPIO numbering can change if other GPIO drivers are probed
- it requires extra steps to set the GPIO direction and value

The new functions have a dm_ prefix where necessary to avoid name conflicts
but we can remove that when it is no-longer needed. The new struct gpio_desc
holds all required information about the GPIO. For now this is intended to
be stored by the client requesting the GPIO, but in future it might be
brought into the uclass in some way.

With these changes the old GPIO API still works, and uses the driver model
API underneath.

For GPIOs and other functions we want to look up a phandle and then decode
a list of arguments for that phandle. Each phandle can have a different
number of arguments, specified by a property in the target node. This is
the "#gpio-cells" property for GPIOs.

Add a function to provide this feature, taken modified from Linux 3.18.

The common/board_r.c has show_model_r() to display the model name
if the DTB has a "model" property.  It sounds useful to have a similar
function in common/board_f.c too because most of the boards show
their board name before relocation.

Instead of implementing the same function in both common/board_f.c
and common/board_r.c, let's split it up into common/show_board_info.c.

Microblaze currently doesn't use printf in SPL. So this one line was the only

Exceeding the 4k size limit. Lets change the printf back to puts so that
Microblaze is fixed again. The only drawback is that the detected boot-device
number will not be printed. But this message alone should be helpful enough
to get an idea where the boot process is broken.
