[ 019/136 ] usb: remove redundant tdi_reset

From: Steven Rostedt
Date: Fri May 17 2013 - 22:28:09 EST stable review patch.
If anyone has any objections, please let me know.


From: Shengzhou Liu <Shengzhou.Liu@xxxxxxxxxxxxx>

[ Upstream commit 61ac6ac8d662ac7ac67c864954d39d1b19948354 ]

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.
