Subject: [PATCH v3 2/3] arm64: dts: qcom: Add header file for IPCC physical
 client IDs on Kaanapali platform

On earlier platforms, Inter Process Communication Controller (IPCC) used
virtual client IDs and performed virtual-to-physical mapping in hardware,
so the IDs defined in dt-bindings/mailbox/qcom-ipcc.h are common across
platforms. Physical client IDs instead of virtual client IDs are used for
qcom new platforms like Kaanapali, which will be parsed by the devicetree
and passed to hardware to use Physical client IDs directly. Since physical
client IDs could vary across platforms, add a corresponding header file
for the Kaanapali platform.
