We remove the redundant tdi_reset in ehci_setup since there
is already it in ehci_reset.
It was observed that the duplicated tdi_reset was causing
the PHY_CLK_VALID bit unstable.

This should be applied to stable kernels going back to 3.6.
In case you are wondering why that redudant call was added, I did it
because some of the PCI drivers (Intel and TDI) already had calls to
tdi_reset. The commit removed those calls, so the new one was added
in.
