Subject: [PATCH v3 1/2] dt-bindings: soc: qcom: Add qcom,kaanapali-imem
 compatible

Document qcom,kaanapali-imem compatible. Kaanapali IMEM is not a syscon or
simple-mfd, also "reboot reason" is not required on Kaanapali like some
other platforms. So define a common "qcom,imem" binding and fallback to it.
Currently there is no requirement for any specific implementation for the
"qcom,imem". Its child node "qcom,pil-reloc-info" has no implementation
dependency on IMEM.
