Subject: [PATCH 4.4 017/312] MIPS: BMIPS: Pretty print BMIPS5200 processor name

From: Florian Fainelli <f.fainelli@...il.com>

commit 37808d62afcdc420d98875c4b514c178d56f6815 upstream.

Just to ease debugging of multiplatform kernel, make sure we print
"Broadcom BMIPS5200" for the BMIPS5200 implementation instead of
Broadcom BMIPS5000.
