Shouldn't that go directly before or after the sama5d4 family ?

I think that at some point we'll have to kill those AT91_DEBUG_LL_*
which are actually board specific and not soc specific. I already have a
patch for that that I need to rebase.

Seeing that, I think HAVE_AT91_GENERATED should include CLK somewhere in
the name as this is only related to clocks.
