Subject: [PATCH] usb: Don't make USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI depend on USB_SUPPORT.

From: David Daney <david.daney@...ium.com>

The fact that an architecture/board has OHCI or EHCI does not depend on
the fact that the kernel is configured with USB_SUPPORT.

Make the Kconfig reflect this fact thus avoiding ugly messages like:

warning: (MIPS_ALCHEMY && CAVIUM_OCTEON_REFERENCE_BOARD && SOC_AR71XX && SOC_AR724X && SOC_AR913X && SOC_AR933X) selects USB_ARCH_HAS_EHCI which has unmet direct dependencies (USB_SUPPORT)
