Placement of aliases is cause for a lot of discussion :-).
Most recently in [0]. And while devices such as mmc controllers do have
names not following any numbers, this is different for the core
busses/devices like serial, i2c, gpio, spi.

All of those start at number 0 and increment then. And all pieces of
documentation like soc manuals, device schematics as well as pin-header
descriptions for SBCs also use these numbers to identify the controller
instance.

All previous Rockchip socs also carry those core busses in the main dtsi
so that not every board needs to have the exact same aliases defined.

changes in v2:
- reword commit messages to make move vs define explicti (Diederik)
- add review from Dragan
