[PATCH] mips: fix cacheinfo

[PATCH] mips: fix cacheinfo

[Vladimir Kondratiev]

Because CONFIG_OF defined for MIPS, cacheinfo attempts to fill information
from DT, ignoring data filled by architecture routine. This leads to error
reported

 cacheinfo: Unable to detect cache hierarchy for CPU 0

Way to fix this provided in
commit fac51482577d ("drivers: base: cacheinfo: fix x86 with
 CONFIG_OF enabled")

Utilize same mechanism to report that cacheinfo set by architecture
specific function

Applied to mips-fixes.

Thanks,
