#1208951 — [PATCH v3 1/3] ARM: qcom: add SFPB nodes to IPQ806x dts

Add one new node to the ipq806x.dtsi file to declare & register the
hardware spinlock devices. This mechanism is required to be used by
other drivers such as SMEM.

I have this block listed to start at 0x1200000 and used 0x604 as offset
when testing this. In my docs there's nothing in those first 0x600 bytes
though, so this works fine for me.
