dt-bindings: pinctrl: qcom,msm8996: convert to dtschema

Convert Qualcomm MSM8996 pin controller bindings to DT schema.  Keep the
parsing of pin configuration subnodes consistent with other Qualcomm
schemas (children named with '-state' suffix, their children with
'-pins').

-This binding describes the Top Level Mode Multiplexer block found in the
-MSM8996 platform.

-	Definition: the base address and size of the TLMM register space.
-
-- interrupts:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: should specify the TLMM summary IRQ.
-
-- interrupt-controller:

-
-- #interrupt-cells:
-	Usage: required

-		    in <dt-bindings/interrupt-controller/irq.h>
-
-- gpio-controller:
-	Usage: required
-	Value type: <none>
-	Definition: identifies this node as a gpio controller
-
-- #gpio-cells:
-	Usage: required

-

-
-Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-a general description of GPIO and interrupt bindings.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-
-PIN CONFIGURATION NODES:
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
-
-- pins:
-	Usage: required
-	Value type: <string-array>
-	Definition: List of gpio pins affected by the properties specified in
-		    this subnode.
-
-		    Valid pins are:
-		      gpio0-gpio149
-		        Supports mux, bias and drive-strength
-

-		      sdc2_data sdc1_rclk
-		        Supports bias and drive-strength
-
-- function:

-		    specified pins. Functions are only valid for gpio pins.
