ipq806x: Add support for IPQ806x chip family

Patches are generated using the "format-patch" command from the
following location:
*https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base
*rev=0771849495b4128cac2faf7d49c85c729fc48b20
Patches numbered 76/77/102/103 have already been integrated in 3.14.12,
so they're not in this list.

All these patches are either integrated are pending integration into
kernel.org, therefore these patches should go away once the kernel
gets upgraded to 3.16.

Support is currently limited to AP148 board but can be extended to other
platforms in the future.

These changes do not cover ethernet connectivity.

++Qualcomm IPQ8064 TLMM block
++
++Required properties:
++- compatible: "qcom,ipq8064-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.
++
++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 abitrary 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 qcom,pins are:
++  gpio0-gpio68
++   Supports mux, bias, and drive-strength
++
++  sdc3_clk, sdc3_cmd, sdc3_data
++   Supports bias and drive-strength
++
++
++Valid values for function are:
++  mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gsbi1, gsbi2, gsbi4, gsbi5,
++  gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1,
++  spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata,
++  pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt,
++  pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren,
++  pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n,
++  pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold
++
++Example:
++
++	pinmux: pinctrl@800000 {
++		compatible = "qcom,ipq8064-pinctrl";
++		reg = <0x800000 0x4000>;
++
++		gpio-controller;
++		#gpio-cells = <2>;
++		interrupt-controller;
++		#interrupt-cells = <2>;
++		interrupts = <0 32 0x4>;
++
++		pinctrl-names = "default";
++		pinctrl-0 = <&gsbi5_uart_default>;
++
++		gsbi5_uart_default: gsbi5_uart_default {
++			mux {
++				pins = "gpio18", "gpio19";
++				function = "gsbi5";
++			};
++
++			tx {
++				pins = "gpio18";
++				drive-strength = <4>;
++				bias-disable;
++			};
++
++			rx {
++				pins = "gpio19";
++				drive-strength = <2>;
++				bias-pull-up;
++			};
++		};
++	};
