[PATCH] drivers/base: cacheinfo: remove noisy error boot message

[Sudeep Holla]

On systems that don't support cacheinfo, this error message can be
considered noisy and irrelevant. The error messages can be added to
the functions that architectures implement overiding the weak default
definition if really required.

This patch removes the concerned error message in the generic code.

Hi Greg,

Since I always tested the series only on the architectures supporting
cacheinfo, I failed to see that this error message is thrown out at the
boot time if the architecture doesn't support it.

Can you pick up this small fix to avoid noisy error message ?

Regards,
Sudeep
