clk: max77686: Avoid double free at remove time
The clk_lookup entry is dropped at remove time by a call to
clkdev_drop(). That function frees the entry, which is also freed by the
driver core as it has been allocated through devm_kzalloc(). This
results in a double free.
Use kzalloc() instead of devm_kzalloc() to fix this.
