[PATCH v3 06/10] clk: clock-wizard: Remove the hardcoding of the clock outputs

[shubhrajyoti.datta@gmail.com]

From: Shubhrajyoti Datta <shubhrajyoti.datta@xilinx.com>

The number of output clocks are configurable in the hardware.
Currently the driver registers the maximum number of outputs.
Fix the same by registering only the outputs that are there.
