Seaboard uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.
Two data sources were used for the data encoded here:
* The HW defaults, as extracted from real HW.
* The schematic, which specifies a voltage for each LDO rail.
In most cases these sources matched. The only differences is:
ldo6: The HW default on Springbank is 2.85v. The HW default on Seaboard
is 1.8v. The schematics for both Springbank and Seaboard match at 2.85v.
However, internal research indicates that the schematics are incorrectly
labelled, and 1.8v is correct. The ChromeOS kernel also uses 1.8v.
Note that these settings don't entirely match those in the ChromeOS
kernel found at the URL below. However, the selected values generally
cause no behavior change in the kernel, and so were picked to avoid
regressions.

Cadhu have multiple power rails which are controlled by
GPIOs. Add support of these power rail control through
fixed regulators. Add entry for all fixed regulators for
cardhu-a02 and a04.
The details are taken from downstream kernel.
Some points on this change are:
* Add the tps65910-LDO5 entry and make it always ON
to supply power to SDMMC. Once the sd driver support
regulator handling, this flag will be remove.
* Dropping registration of rail vdd_sdmmc1 as the gpio
is used by sdhci power-gpio. This need to fix in
sdhci driver and then need to add the registration
mechanism. Just removing power-gpio and adding fixed
regulator with this gpio is causing the sd access to
fail because first probe call of this regulator fails
due to non-available of parent and so it calls
gpio_free() which disable the pins in gpio mode make
pin output to LOW causes power to OFF. In probe retry,
it got success and it powered-on but it again need to
do again numeration of card here.

There is multiple version of cardhu starting from A01 to A07.
Cardhu A01 and A03 are not supported. Cardhu A02 will have
different sets of GPIOs for fixed regulator compare to
cardhu A04. The Cardhu A05, A06, A07 are compatibe with A04.
Based on cardhu version, the related dts file need to be chosen
like for cardhu A02, use tegra30-cardhu-a02.dts, cardhu A04 and
more, use tegra30-cardhu-a04.dts.
This patch create the DTS file A02 and A04 and convert tegra30-cardhu.dts
as dts include file.

Tegra30 based platform "cardhu" have the power management
IC TPS65911 for the regulator.
Adding DT entry for this device.
Data are chosen from downstream kernel and making the
voltage output as require by default for device to
operate.
The default interrupt line is HIGH from PMIC device and so
inverting the interrupt detection line of PMU interrupt
through configuring PMC.
In this patch, do not registering LDO5 because the input
supply for this rail is different for different version of
cardhu i..e A02 and A04. The registration will be done once
the dts file for cardhu A02 and A04 are added in follow on
patches.

For non-DT boot, function tx28_add_fec0 configures all ENET0 pins
into gpio mode for resetting fec phy, and then reconfigures those pins
into ENET function after that.
For DT boot, all the pin configuration is done by pinctrl subsystem.
Ideally, when gpio_request gets called, GPIO subsystem should call
pinctrl to configure pins into gpio mode automatically, and have pins
freed up from pinctrl subsystem when gpio_free is called. But right
now, this cooperation between gpio and pinctrl hasn't been available.
As the result, we have to explicitly call pinctrl_get_select and
pinctrl_put for device tree boot.
