Add device tree binding for NAND on the BCM6368.

The BCM6368 has a NAND interrupt register with combined status and enable
registers. It also requires a clock, so add an optional clock to the
common brcmnand binding.

As noted here [1], there are potentially future conflicts if we try to
use MTD's "partitions" subnode to describe anything besides just the
fixed-in-the-device-tree partitions currently described in this
document. Particularly, there was a proposal to use this node for the
AFS parser too.

It can pose a (small) problem to try to differentiate the following
nodes:

	// using binding as currently specified
	partitions {
		#address-cells = <x>;
		#size-cells = <y>;
		partition@0 {
			...;
		};
	};

and

	// proposed future binding
	partitions {
		compatible = "arm,arm-flash-structure";
	};

It's especially difficult if other uses of this node start having
subnodes.

So, since the "partitions" node is new in v4.4, let's fixup the binding
before release so that it requires a compatible property, so it's much
clearer to distinguish. e.g.:

	// proposed
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <x>;
		#size-cells = <y>;
		partition@0 {
			...;
		};
	};

This change turns the UFS variant (SCSI_UFS_QCOM) into a UFS
a platform device.
In order to do so a few additional changes are required:
1. The ufshcd-pltfrm is no longer serves as a platform device.
   Now it only serves as a group of platform APIs such as PM APIs
   (runtime suspend/resume, system suspend/resume etc), parsers of
   clocks, regulators and pm_levels from DT.
2. What used to be the old platform "probe" is now "only"
   a pltfrm_init() routine, that does exactly the same, but only
   being called by the new probe function of the UFS variant.

The "init" pinctrl is defined we'll set
pinctrl to this state before probe and then "default" after probe.
Add the "init" and "sleep" pinctrl as the OTP gpio state, since we need
switch the pin to gpio state before the TSADC controller is reset.

AFAIK, the TSADC controller is reset, the tshut polarity will be
a *low* signal in a short period of time for some devices.

Says:
The TSADC get the temperature on rockchip thermal.

If T(current temperature) < (setting temperature), the OTP output the
*high* signal.
If T(current temperature) > (setting temperature), the OTP output the
*low* Signal.

In some cases, the OTP pin is connected to the PMIC, maybe the
PMIC can accept the reset response time to avoid this issue.

In other words, the system will be always reboot if we make the
OTP pin is connected the others IC to control the power.
