Mukesh Ojha bc3c98b776 dt-bindings: firmware: qcom,scm: Add minidump SRAM property
On Qualcomm SoCs that support minidump, a word in always-on SRAM
is shared between the Operating System(HLOS) and boot firmware.
OS is expected to select the minidump download destination
either USB upload to a host PC or save to on-device storage.
Boot firmware will reads this word before DDR is initialized
on the warm reset following a crash to decide where to deliver
the minidump.

Add a 'sram' property to the SCM binding to allow the OS to
identify this SRAM region via a phandle.
