Dear Dave Mitchell,

Current de-assert reset is not sufficient for the USB PHY reset on some Canyonlands platforms. The patch adds an assert/de-assert sequence. This addresses a USB detection problem for devices attached prior to power-up. The delay lengths are needed for power to the PHY to stabilize.

v1->v2: fixed typo
NAK again. This does not belong in generic board init code.
I see. Are you asking that all of the USB code be removed? Including the previous PHY reset implementation done by the original Canyonlands port (toggling the CPLD reset for the PHY).
