[PATCH v4 16/19] arm64: dts: qcom: sm6350: Add minidump SRAM config to SCM node

[Mukesh Ojha <mukesh.ojha@oss.qualcomm.com>]

Point the SCM node at the minidump config slot in the always-on SRAM.
Boot firmware reads this word before DDR is initialised on a warm reset
to decide where to deliver the minidump.
