[PATCH V2 04/10] board: ti: am64x: Set fdtfile from C code instead of findfdt script

[Nishanth Menon <nm@ti.com>]

We now can provide a map and have the standard fdtfile variable set from
code itself. This allows for bootstd to "just work".

While at this, replace findfdt in environment with a warning as it is no
longer needed.

Changes from V1: None.
I have retained the the existing names used in the file as is for now, a
cleanup as suggested in review is probably something to do in a follow
on series.
