USB: EHCI: export ehci_handshake for ehci-hcd sub-drivers
In order to split ehci-hcd.c into separate modules, handshake() must be
exported. Rename the symbol to add an ehci_ prefix, to avoid any naming
clashes.

[swarren, split Manjunath's patches more logically, limit this change
to export just handshake()]
