Subject: [PATCH v3 0/4] Add larbid init routine for mediatek's gen1 smi larb driver

From: Honghui Zhang <honghui.zhang@...iatek.com>

Mediatek's gen1 smi need the hardware larb-id to identify the offset for
the register which controls whether enable iommu for this larb.
In the commit 3c8f4ad85c4b ("memory/mediatek: add support for mt2701"),
the larbid was used without properly initialized. This patchset fixed
that.
Also include a patch which using the of_device_get_match_data helper to
simplify the code.
This patchset was base on 4.13-rc1.

Change since v2:
 - Using compatible strings of "mediatek,larb-id" instead of "mediatek,larbid"
   to make it a bit easier to read.
 - Put the v2 of the patch ("memory: mtk-smi: Use of_device_get_match_data helper")[1]
   in this patchset to make the changes easier for review.
 - Add the reivewer's tag in commit messages.

Change since v1:
 - Using mtk_smi_larb_gen to identify whether larbid was needed instead of
   checking hard code bindings.
