This patch switches MTK_SMI to tristate. Support it could be 'm'.

Meanwhile, Fix a build issue while MTK_SMI is built as module.

s/Fix/fix.

What error is being fixed here? How can I reproduce it? Aren't you just
adjusting it to being buildable by module?

Sorry, I didn't copy the fail log here. This is the build log:

In file included from .../drivers/iommu/mtk_iommu.c:34:0:
.../drivers/iommu/mtk_iommu.h:84:28: error: array type has incomplete
element type 'struct mtk_smi_larb_iommu'
  struct mtk_smi_larb_iommu larb_imu[MTK_LARB_NR_MAX];

Our iommu driver will use this structure. but it was contained by
"#ifdef CONFIG_MTK_SMI". thus I change it to "#if
IS_ENABLED(CONFIG_MTK_SMI)"

If reproducing it, we should change mtk-iommu to module_init[1]. and
switch kconfig MTK_IOMMU to tristate, then change the CONFIG_MTK_IOMMU
to m. we could get the fail log.

In this case, Should I squash this change into this patch? I though this
is a preparing patch and the fail is caused by MTK_SMI. thus I squash
that into this patch. or change it as a independent patch and send when
I change MTK_IOMMU to tristate?

If I understand correctly, there is no error before this patch. In such
case just don't mention the error to fix, because it is simply part of
making things modular.

Yes. No error before this patch.

Appreciate for your help. I will remove this in the comment message in
the next version.

Best regards,
Krzysztof
