Rather than have separate opaque setter functions that are easy to
overlook and lead to repetitive boilerplate in drivers, let's pass the
relevant initialisation parameters directly to iommu_device_register().

It happens that the 3 drivers which first supported being modular are
also ones which play games with their pgsize_bitmap, so have non-const
iommu_ops where dynamically setting the owner manages to work out OK.
However, it's less than ideal to force that upon all drivers which want
to be modular - like the new sprd-iommu driver which now has a potential
bug in that regard - so let's just statically set the module owner and
let ops remain const wherever possible.

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.

There is a spelling mistake in a dev_err message. Fix it.

This IOMMU module can be used by Unisoc's multimedia devices, such as
display, Image codec(jpeg) and a few signal processors, including
VSP(video), GSP(graphic), ISP(image), and CPP(camera pixel processor), etc.
