Adding an unused .dtsi duplicating GXBB makes me uneasy.

Any chance we can simplify this to at most two steps?
1) Move code from gxbb to gx (1/3 + 3/3)
2) Add gxl using gx ("Add basic support for Amlogic S905X" + 2/3)

Alternatively:
1) "Add basic support for Amlogic S905X"
2) Factor out common bits (1/3 + 2/3 + 3/3)

As for bike-shedding, is there a GX family as well or could we drop
-common? .dtsi is always something common - compare Exynos or i.MX.
Since there are meson8b and meson8 I was anticipating that after gxbb
would come gx, not gxl.

Do you know what the L in GXL is for? Should we consider renaming gxbb
to gxb, and then also insert -s905 as suggested by Kevin, for symmetry?
U-Boot is still in an early stage with $fdtfile issues remaining that I
need to iterate over; DT compatible strings would need to remain though.

Regards,
Andreas
