Currently, most of the pr_* messages in the GICv3 driver don't have a
prefix.  Add one to make clear where the messages come from.

I don't think this patch is needed, as GICv3 and GICv2 will
not be probed at the same time, did I miss something?

Further more, there are prefixes in pr_fmt in this
patch using GIC:, with your patch added, it will print:

GIV3: GIC: .....

which is not a good idea.

Thanks
Hanjun

Hi Hanjun,

Sorry for the late answer.

True, however this make slightly easier to know which driver is in-use 
and avoid to prefix all the messages with "GIC:" or "GICv3:".

I think it is better than having message without prefix at all.
