[PATCH 1/4] usb: Move SPL_USB_HOST Kconfig symbol to drivers/usb/

[Marek Vasut <marex@denx.de>]

To avoid piling up all the various Kconfig symbols in one place, i.e.
common/spl/Kconfig, move the USB Kconfig symbols into drivers/usb/ .
This commit moves SPL_USB_HOST and updates help text of both USB_HOST
and SPL_USB_HOST .
