[PATCH v3 02/18] dt-bindings: sram: qcom,imem: Add minidump-sram pattern property

[Mukesh Ojha]

Add a patternProperty for the minidump-sram child node to the qcom,imem
binding that describes a single word in always-on SRAM shared between
the kernel and boot firmware. Before DDR is initialized on the warm
reset following a crash, firmware reads this word to decide where to
deliver the minidump (USB or on-device storage).
