rmobile: armadillo-800eva: Change init function of SCIFA1

This initializes GPIO, without using PFC framework in board_early_init_f function. It is because it cannot initialize normally when PFC is used. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
