We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).
It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.
For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

This patch is the start of a series to change all non-x86 SoC-specific
headers to be included as <soc/header.h> instead of the old
<soc/vendor/chip/header.h> or "header.h". It will add an include/soc/
directory under every src/soc/vendor/chip/ and append the .../include/
part of that to the global include path.
This matches the usage of <arch/header.h> for architecture-specific
headers and had already been done for some headers on Tegra. It has the
advantage that a source file which does not know the specific SoC used
(e.g. Tegra files common for multiple chips, or a global include file)
can still include SoC-specific headers and access macros/types defined
there. It also makes the includes for mainboard files more readable, and
reduces the chance to pull in a wrong header when copying mainboard
sources to use a different-related SoC (e.g. using a Tegra124 mainboard
as template for a Tegra132 one).
For easier maintainability, every SoC family is modified individually.
This patch starts out by changing Rk3288. Also alphabetized headers in
affected files since we touch them anyway.
BUG=None
TEST=Whole series: compared binary images for Daisy, Nyan_Blaze,
Rush_Ryu, Storm, Urara and Veyron_Pinky. Confirmed that they are
byte-for-byte identical except for timestamps, hashes, and __LINE__
macro replacements. Compile-tested individual patches.

This patch adds support for the board changes in rev2 (board_id = 0001).
It also moves the existing mainboard.c code around a bit to group it by
component.

TEST=Booted on rev1. Confirmed SD card still works. Confirmed power
button was still as broken as before.
