board: renesas: ebisu: Drop CA57 check in reset_cpu()

Browse source 
Renesas Ebisu board is based on R-Car E3 SoC which has dual CA53 and
a CR7.

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.
