Exynos5420 based Peach Pit and Exynos5800 based Peach Pi boards
uses a Maxim 77802 power management IC to drive regulators and
its Real Time Clock. This patch adds support for this chip.

These are the device nodes and pinctrl configuration that
are present on the Peach pit DeviceTree source file in the
the Chrome OS kernel 3.8 tree.

The DeviceTree files for the Peach Pit and Pi machines have
a simplistic model of the connections between the different
regulators since not all the tps65090 regulators get their
input supply voltage from the VDC. DCDC1-3, LD0-1 and fet7
parent supply is indded VDC but the fet1-6 get their input
supply from the DCDC1 and DCDC2 output voltage rails.

Update the DeviceTree to better reflect the real connections
between tps65090 regulators. Having this information in the
DTS is useful since FETs are switches that don't provide an
output voltage so the regulator core needs to fetch the FET
parent output voltage if the child voltage is queried.

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".

This adds cros_ec to exynos5420-peach-pit and exynos5800-peach-pi,
including:
* The keyboard
* The i2c tunnel
* The tps65090 under the i2c tunnel
* The battery under the i2c tunnel

To add extra motivation, it should be noted that tps65090 is one of
the things needed to get display-related FETs turned on for pit and
pi.

The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from
being reset across sleep/wake.  If we don't set it to anything then
the TPM will be reset.  U-Boot will detect this as invalid
and will reset the system on resume time. This GPIO can always be low
and not hurt anything.  It will get pulled back high again during a
normal warm reset when it will default back to an input.

To properly preserve the TPM state across suspend/resume and to make
the chrome U-Boot happy, properly set the GPIO to mask the
reset to the TPM.

Peach-pit and Peach-pi boards are almost similar, hence the DTS file
is also very similar. Sorting nodes in both these files will allow
us to figure out the difference easily.

All the node aliases are sorted in alphabetically increasing order.
There is no functional change with this patch.
