[PATCH 1/3] driver: support Linux device/driver OF struct member names

[Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx>]

When porting drivers from Linux, one of the modifications that needs to
be done is to rename all .of_node to .device_node and of_match_table
to of_compatible. Just accept both names. It comes at no extra cost.

Once all barebox drivers use the Linux naming, we could drop the union
again.
