[PATCH 3/3] sh/intc: Add a space character for better code readability in register_intc_controller()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 13 Jan 2017 10:32:04 +0100

The script "checkpatch.pl" pointed information out like the following.

ERROR: spaces required around that '+=' (ctx:VxW)

Thus fix the affected source code place.
