[PATCH] ARM: boards: sama5d4 xplained: Use proper header for image start

[Alexander Shiyan <eagle.alexander923@gmail.com>]

Switch to using the SAMA5D4-specific entry function and barebox header
instead of the generic ARM entry points. This aligns the board with
standard AT91 bootstrap practices.
The board is already marked BROKEN, so this refactoring won't cause
regressions but improves code consistency with other AT91 boards.
