[PATCH V2 03/10] board: ti: am62x: Set fdtfile from C code instead of findfdt script

Stop using the findfdt script and switch to setting the fdtfile from
C code.

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

Changes from V1: None.
I have retained the central call ti_set_fdt_env() to retain the
population of fdtfile name using the CONFIG fall back logic and the
population of (now deprecated) legacy variables for downstream script
users.
