usb: ehci-omap: Don't softreset USB High-speed Host (UHH) Module Fixes NFS root problems with Beagle (3530 ES1.0) when used with external USB-ethernet adapter and "USB start" command used within u-boot. Soft resetting the UHH module causes instability issues on all OMAPs so we just avoid it. See OMAP36xx Errata i571: USB host EHCI may stall when entering smart-standby mode i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock On OMAP4/5, soft-resetting the UHH module can put it into Smart-Idle mode and lead to a deadlock. On OMAP3 this doesn't seem to be the case but still instabilities are observed on beagle (3530 ES1.0) if soft-reset is used. e.g. NFS root failures with Linux kernel.
