[PATCH V2 1/3] dt-bindings: sram: qcom,imem: Add Boot Stat region within IMEM

[Souradeep Chowdhury]

All Qualcomm bootloaders log useful timestamp information related
to bootloader stats in the IMEM region. Add the child node within
IMEM for the boot stat region containing register address and
compatible string.
