Convert Qualcomm MSM8660 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').

-Qualcomm MSM8660 TLMM block
-
-Required properties:
-- compatible: "qcom,msm8660-pinctrl"
-- reg: Should be the base address and length of the TLMM block.
-- interrupts: Should be the parent IRQ of the TLMM block.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be two.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two.
- The first cell is the gpio pin number and the
- second cell is used for optional parameters.
-- gpio-ranges: see ../gpio/gpio.txt
-
-Optional properties:
-
-- gpio-reserved-ranges: see ../gpio/gpio.txt
-
-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".
-
-Qualcomm's 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.
-
-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, function, bias-disable, bias-pull-down, bias-pull-up, drive-strength,
- output-low, output-high.
-
-Non-empty subnodes must specify the 'pins' property.
-
-Valid values for pins are:
- gpio0-gpio172, sdc3_clk, sdc3_cmd, sdc3_data sdc4_clk, sdc4_cmd, sdc4_data
-
-Valid values for function are:
- gpio, cam_mclk, dsub, ext_gps, gp_clk_0a, gp_clk_0b, gp_clk_1a, gp_clk_1b,
- gp_clk_2a, gp_clk_2b, gp_mn, gsbi1, gsbi1_spi_cs1_n, gsbi1_spi_cs2a_n,
- gsbi1_spi_cs2b_n, gsbi1_spi_cs3_n, gsbi2, gsbi2_spi_cs1_n, gsbi2_spi_cs2_n,
- gsbi2_spi_cs3_n, gsbi3, gsbi3_spi_cs1_n, gsbi3_spi_cs2_n, gsbi3_spi_cs3_n,
- gsbi4, gsbi5, gsbi6, gsbi7, gsbi8, gsbi9, gsbi10, gsbi11, gsbi12, hdmi, i2s,
- lcdc, mdp_vsync, mi2s, pcm, ps_hold, sdc1, sdc2, sdc5, tsif1, tsif2, usb_fs1,
- usb_fs1_oe_n, usb_fs2, usb_fs2_oe_n, vfe, vsens_alarm, ebi2, ebi2cs
-

-
- msmgpio: pinctrl@800000 {
