[PATCH] powerpc/setup: Adjust six seq_printf() calls in show_cpuinfo()

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 2 Jul 2019 14:41:42 +0200

A bit of information should be put into a sequence.
Thus improve the execution speed for this data output by better usage
of corresponding functions.

This issue was detected by using the Coccinelle software.
