misc: hisi_hikey_usb: remove untested role-switch driver

Browse source

During review of a lifetime fix for this driver, it turned out that the
role-switch path has no upstream DT binding or in-tree user and has not
been tested in years.

Rather than keep carrying and fixing an effectively unused board-specific
driver, remove it. If this functionality is needed again later, it can be
reintroduced in drivers/phy/, where USB role-switch support lives today.
