[RFC PATCH v2 0/3] support Samsung Exynos xHCI Controller

[Daehwan Jung]

This patchset is to support xHCI Controller on Samsung Exynos SOCs.
Thanks for all reviews on v1 and have tried to modify it well.
I again added "RFC" because I haven't solved below problem when checking dt bindings.

usb@4a000000: #size-cells:0:0: 0 was expected
Documentation/devicetree/bindings/usb/snps,dwc3.yaml

Changes in v2 :
- Rename subject of cover letter
    ([RFC,v1,0/2] add xhci-exynos to support Samsung Exynos SOC)
- Add Exynos compatible in xhci platform driver instead making new platform driver.
- Make xhci platform driver as child of dwc3 with DT schema.
- Override roothub ops for xhci platform driver.
