Use the <dt-bindings/gpio/gpio.h> header instead of using
hardcoded values for the GPIO flags. Eradicate the totally
bogus "0x4" flag used and set that to GPIO_ACTIVE_HIGH as is
proper, switch the inverted card detect on the Snowball to
flag using GPIO_ACTIVE_LOW instead of using the MMC-specific
inversion flag.

The Snowball gyro and magnetometer DRDY (data ready) lines are used
as interrupt triggers by the IIO subsystem, triggering new data
retrieveal on edges on this signal. Thus assign them as the primary
interrupt in the device tree. The "other interrupt" coming out of
the sensors is for alarms and similar complex events, the DRDY is
for periodic measures, which is what we want.

After this the generic_buffer tool from IIO tools gives a nice
stream of readings after enabling the desired channels in sysfs.

The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"

However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.

This patch fixes it by making use of "wakeup-source" property.

Ux500 is regressing due to commit
a21763a0
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.

The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).

The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.

To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

The Ux500 boards are layered like this:
ste-snowball.dts includes ste-href.dtsi that includes
ste-dbx500.dtsi.

The dbx500.dtsi defines the PRCMU SoC regulators so the SoC will
probe and you can use ampersand references where need be.

However the HREF common dtsi and these two boards redefine the
same PRCMU SoC regulators with the very same names and properties
for no reason. This is like filling in the same line three
times instead of drawing it once. Just delete the surplus
references and have the PRCMU regulators defines in the SoC
files ste-dbx500.dtsi, this is enough.

When this node was added, the AB8500 GPIO driver was pretty broken.
As a hack, we pretended that NOMADIK GPIO 26 was the correct on/off
pin, as it was unused. It worked because AB8500 GPIO 26 was in an
'always on from boot' state. Now the AB8500 GPIO driver is working,
the default state for all the pins is 'off'. Let's flip back over to
use the correct GPIO which is _actually_ attached to the regulator.

We're also taking the opportunity to straighten out some formatting
