iommu/sprd: Fix parameter type warning 



The second parameter of clk_get_optional() is "const char *", so use NULL
instead of integer 0 to fix a sparse warning like:

">> drivers/iommu/sprd-iommu.c:456:42: sparse: sparse: Using plain integer as NULL pointer"

Also this patch changes to use the resource-managed variant of
clk_get_optional(), then there's no need to add clk_put() which
is missed in the current driver.
