[PATCH] clk: hisilicon: reset: Use kzalloc instead of kmalloc

[Shawn Guo <shawnguo@kernel.org>]

With commit c721f189e89c ("reset: Instantiate reset GPIO controller for
shared reset-gpios") in place, the call sequence hisi_reset_init() ->
reset_controller_register() starts failing on Hi3798CV200 Poplar platform,
due to the new check added by the commit above.

	if (rcdev->of_node && rcdev->of_args)
		return -EINVAL;

The failure is caused by that hisi_reset_init() allocates memory for rcdev
without zeroing it out.  Fix the issue by using kzalloc instead of
kmalloc for memory allocation.
