Subject: [PATCH 03/30] clk: xilinx: Drop if block with always false condition

xvcu_remove() is only called for a device after after xvcu_probe()
completed successfully. In that case dev_set_drvdata() was called for
that device with a non-NULL parameter, so platform_get_drvdata() won't
return NULL and the if condition is never true.

Drop the if, preparing a conversion to make platform driver's remove
callback return void.
