doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1570617

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

-Qualcomm Shared Memory Point 2 Point binding
-
-The Shared Memory Point to Point (SMP2P) protocol facilitates communication of
-a single 32-bit value between two processors.  Each value has a single writer
-(the local side) and a single reader (the remote side).  Values are uniquely
-identified in the system by the directed edge (local processor ID to remote
-processor ID) and a string identifier.
-
-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: must be one of:
-		    "qcom,smp2p"
-
-- interrupts:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: one entry specifying the smp2p notification interrupt
-
-- mboxes:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: reference to the associated doorbell in APCS, as described
-		    in mailbox/mailbox.txt
-
-- qcom,ipc:
-	Usage: required, unless mboxes is specified
-	Value type: <prop-encoded-array>
-	Definition: three entries specifying the outgoing ipc bit used for
-		    signaling the remote end of the smp2p edge:
-		    - phandle to a syscon node representing the apcs registers
-		    - u32 representing offset to the register within the syscon

-Each SMP2P pair contain a set of inbound and outbound entries, these are

-important.
-
-- qcom,entry-name:
-	Usage: required
-	Value type: <string>
-	Definition: specifies the name of this entry, for inbound entries this
-		    will be used to match against the remotely allocated entry
-		    and for outbound entries this name is used for allocating
-		    entries
-
-- interrupt-controller:
-	Usage: required for incoming entries
-	Value type: <empty>
-	Definition: marks the entry as inbound; the node should be specified
-		    as a two cell interrupt-controller as defined in
-		    "../interrupt-controller/interrupts.txt"
-		    If not specified this node will denote the outgoing entry
-
-- #interrupt-cells:
-	Usage: required for incoming entries
-	Value type: <u32>
-	Definition: must be 2 - denoting the bit in the entry and IRQ flags
-
-- #qcom,smem-state-cells:
-	Usage: required for outgoing entries
-	Value type: <u32>
-	Definition: must be 1 - denoting the bit in the entry
