dt-bindings: soc: qcom: Introduce Glink Pkt bindings 

The RPMSG char driver requires clients to ioctl into a ctrl node to
create corresponding userspace char devices. Not all GLINK clients can
follow this standard. Add the GLINK PKT driver to create char devs from
boot time.

[Root level node]

Required properties:

-compatible : should be "qcom,glinkpkt"



[Second level nodes]

qcom,glinkpkt-channel-names

Required properties:

-qcom,glinkpkt-transport : the glinkpkt transport layer

-qcom,glinkpkt-edge : the remote subsystem name

-qcom,glinkpkt-ch-name : the glink channel name

-qcom,glinkpkt-dev-name : the glinkpkt device name



Example:



         qcom,glink_pkt {

                 compatible = "qcom,glinkpkt";



                 qcom,glinkpkt-at-mdm0 {

                         qcom,glinkpkt-transport = "smd_trans";

                         qcom,glinkpkt-edge = "mpss";

                         qcom,glinkpkt-ch-name = "DS";

                         qcom,glinkpkt-dev-name = "at_mdm0";

                 };



                 qcom,glinkpkt-loopback-cntl {

                         qcom,glinkpkt-transport = "lloop";

                         qcom,glinkpkt-edge = "local";

                         qcom,glinkpkt-ch-name = "LOCAL_LOOPBACK_CLNT";

                         qcom,glinkpkt-dev-name = "glink_pkt_loopback_ctrl";

                 };



                 qcom,glinkpkt-loopback-data {

                         qcom,glinkpkt-ch-name = "glink_pkt_lloop_CLNT";

                         qcom,glinkpkt-dev-name = "glink_pkt_loopback";
