drivers: add a snapshot of various QPNP PMIC peripheral drivers

* msm-qpnp-pin

msm-qpnp-pin is a GPIO chip driver for the MSM SPMI implementation.

It creates a platform_device for every block of device_nodes.

These device_nodes contained within specify the PMIC pin number associated

with each gpio chip. The driver will map these to Linux GPIO numbers.

                          active configuration defined for each pin or pin group.

                          "strobe_disable" : pinctrl config to disable hw-strobe. This should specify the

                          sleep configuration defined for each pin or pin group.

- qcom,hw-strobe-gpio	: phandle to specify GPIO for hardware strobing. This is used when there is no

			  pinctrl support or PMIC GPIOs are used.

- qcom,hw-strobe-sel	: Boolean property to enable hardware strobe. If not defined, software strobe

			  will be used.

- qcom,hw-strobe-edge-trigger	: Boolean property to select trigger type. If defined, hw-strobe is set to

				  be edge triggered. Otherwise, it is level triggered.

- qcom,hw-strobe-active-low	: Boolean property to select strobe signal polarity. If defined, hw-strobe

				  signal polarity is set to active-low, else it is active-high.

	qcom,leds@d300 {
