USB: ehci tdi : let's tdi_reset set host mode
tdi_reset is already taking care of setting host mode for tdi devices.
Don't duplicate code in platform driver.
Make ehci_halt a nop if the controller is not in host mode (otherwise it
will fail), and let's ehci_reset do the tdi_reset.
We need to move hcd->has_tt flags before ehci_halt, in order ehci_halt
knows we are a tdi device.
Before the setup routine was doing :
- put controller in host mode
- ehci_halt
- ehci_init
- hcd->has_tt = 1;
- ehci_reset
Now we do :
- hcd->has_tt = 1;
- ehci_halt
- ehci_init
- ehci_reset
PS : now we handle correctly the device -> host transition.
