This series adds support for several popular Amlogic S905X3 (SM1) Android
Set-Top Box devices. Like most Android box devices, they ship in variants
with multiple RAM, eMMC, WiFi and BT configurations. RAM and eMMC are not
something we need to consider to get a working boot, but we do need to get
the correct connectivity spec.

The reason we don't need to care about RAM differences is because u-boot
takes care of that, and updates the DT nodes accordingly.

In general, I'm not a fan of leaving these decisions up to u-boot,
but...  as an option...

I'm pondering if we should do the same for the connectivity settings?  A
properly configured u-boot already knows if it's an internal/external
PHY, Mbit vs Gbit etc. so in a similar way could enable/disable the
right nodes.

We could have a single DTS for each of these board families which
has some reasonable defaults, then u-boot would enable/disable nodes
accordingly.
