[PATCH 3/7] PM / OPP: rename opp_table->clk to opp_table->cur_clk

[aisheng.dong@nxp.com (Dong Aisheng)]

Since we now support per OPP clocks, we rename opp_table->clk to
opp_table->cur_clk to make it less confusing as the opp_table->clk
will become only represent the current clock of the current OPP
on which the device is running.
