Rob, Mark: when there are multiple reg properties, why is the convention
to use the *first* address in the node's name, rather than the lowest


spmi_bus: spmi@800f000 {
compatible = "qcom,spmi-pmic-arb";
reg = <0x0800f000 0x1000>,
<0x08400000 0x1000000>,
<0x09400000 0x1000000>,
<0x0a400000 0x220000>,
<0x0800a000 0x3000>;
reg-names = "core", "chnls", "obsrvr", "intr", "cnfg";

"spmi@800f000" instead of "spmi@800a000"

Especially, since the reg props could be in any order here, given the
lookup by name.
