[PATCH v2] clk: xgene: Delete duplicated name field

From: Matthias Brugger
Date: Wed Jun 17 2015 - 17:29:15 EST


X-Gene clocks implement it's name in the clock private struct.
This is a duplication of the name field. We can delete the field
and rely on the common implementation to retrieve the name.
