Is the default 5,000 or 40,000?? I can't tell.

As noted in the patch description, xhci-plat devices will use a default of
40,000, while MTK devices will use a default of 5,000. This is also documented
in the probe for each relevant driver. This is further confirmed in the
description for each driver's binding TXT file.
