Subject: [PATCH 4.8 089/125] clk: qoriq: fix a register offset error

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tang Yuantian <Yuantian.Tang@....com>

commit 8964193f6bfda5c4cf14eedb7e94892c1f1c34f0 upstream.

The offset of Core Cluster clock control/status register
on cluster group V3 version is different from others, and
should be plus 0x70000.
