[PATCH v2] renesas: rcar: Apply ATF overlay for reserved-memory

[Detlev Casanova]

The function fdtdec_board_setup() is only called by fdtdec_setup() which
needs to be called by the board file.

This is not the case for the renesas boards so rename the
fdtdec_board_setup() function to a local name and call it directly from
ft_board_setup(), before cleaning up the memory nodes.
