[PATCH 07/19] ARM: layerscape: drop wrong errata workaround

[Sascha Hauer <s.hauer@pengutronix.de>]

set_usb_txvreftune() works on the USB Parameter 1 Control Register.
USB Parameter 2 Control Register has a different register layout and
calling set_usb_txvreftune() on it is wrong. Drop the bogus errata
workaround.
