realtek: engenius_ews2910p: support multiple hardware versions

When the Engenius EWS-2910P was added, only v1 was known. Move the
common parts to a dtsi, and split up the support to acccount for the
hardware version.

On v3, for example, the root partition uses a different uImage magic.

Add a "engenius,ews2910p-v1" compatible, while leaving the legacy
"engenius,ews2910p" to also mean v1.
