Subject: [PATCH] pch_phub: add message to notify installing pch_phub

Currently, a user who wants to install pch_phub, the user can't know whether
the driver is installed or not from log of kernel ring buffer.
Of course, though seeing sysfs files, the user can know the installing,
kernel message is useful better than seeing sysfs files.

So, this patch adds logs.
