board: renesas: draak: Drop CA57 reset
Renesas Draak board based on R-Car D3 has single CA53. This patch drops check for cputype from reset_cpu() and also drops the corresponding CA57 macros. While at it also dropped RST_RSTOUTCR macro which is unused. Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> Reviewed-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
