Subject: [PATCH 0/2] arm64: dts: qcom: pmk[345]50: enable reboot reason

Like SA8775P (at [1]), the SM8350, SM8450 & SM8550 platforms uses
the SDAM2 nvmem to pass the reboot reason.

This simply adds the sdam2 and reboot reason nodes
in the pmk8350 and pmk8550 dtsi.

Tested with:

and

triggering the following ABL logs on HDK8450:
  KeyPress:0, BootReason:2
  Fastboot=1, Recovery:0
and
  KeyPress:0, BootReason:1
  Fastboot=0, Recovery:1
