There are tow quirks for DesignWare USB3 DRD Core of Hisilicon Kirin Soc.
1)SPLIT_BOUNDARY_DISABLE should be set for Host mode
2)A GCTL soft reset should be executed when switch mode
Thus, it must be two patches, no?

Redundant parens.

Ditto.

Indentation style is different to the other functions in the same patch.
Use simple space here.

I don't see anything about this change in commit message. Moreoever,
it looks like it must be a separate logical change with its own
description.
