USB: remove CONFIG_USB_PERSIST setting
This patch (as1047) removes the USB_PERSIST Kconfig option, enabling it permanently. It also prevents the power/persist attribute from being created for hub devices; there's no point in having it since USB-PERSIST is always turned on for hubs.

- If you say Y here and enable the "power/persist" attribute
- for a USB device, the device's data structures will remain
- persistent across system suspend, even if the USB bus loses
- power. (This includes hibernation, also known as swsusp or
- suspend-to-disk.) The devices will reappear as if by magic
- when the system wakes up, with no need to unmount USB
- filesystems, rmmod host-controller drivers, or do anything
- else.

- WARNING: This option can be dangerous!

- If a USB device is replaced by another of the same type while
- the system is asleep, there's a good chance the kernel won't
- detect the change. Likewise if the media in a USB storage
- device is replaced. When this happens it's almost certain to
- cause data corruption and maybe even crash your system.
