This is less wrong than v9, but still a little wrong. You should be
keeping these ordered by unit address. 94100000 comes after 84400000.

For completeness sake, I'll also point out that the WiFi node is also
sorted incorrectly. 0x18800000 comes after 0x01500000.

You can skip ^^, its already
present as wlan_mem in the
board dts.
