arm: rmobile: Update print_cpuinfo function
The print_cpuinfo fucntion has same code. It has a code of many common. This adds a table of CPU information, duplicate using for-loop. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
