Fix config warning:
warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies (USB_SUPPORT && USB_ARCH_HAS_HCD)
and build error: ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!
by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.
This exposes: drivers/video/Kconfig:36:error: recursive dependency detected! drivers/video/Kconfig:36: symbol FB is selected by DRM_KMS_HELPER drivers/gpu/drm/Kconfig:28: symbol DRM_KMS_HELPER is selected by DRM_UDL drivers/gpu/drm/udl/Kconfig:1: symbol DRM_UDL depends on USB_ARCH_HAS_HCD drivers/usb/Kconfig:78: symbol USB_ARCH_HAS_HCD depends on USB_ARCH_HAS_OHCI drivers/usb/Kconfig:16: symbol USB_ARCH_HAS_OHCI depends on I2C drivers/i2c/Kconfig:5: symbol I2C is selected by FB_DDC drivers/video/Kconfig:86: symbol FB_DDC is selected by FB_CYBER2000_DDC drivers/video/Kconfig:385: symbol FB_CYBER2000_DDC depends on FB_CYBER2000 drivers/video/Kconfig:373: symbol FB_CYBER2000 depends on FB
which is due to drivers/usb/Kconfig: config USB_ARCH_HAS_OHCI ... default y if ARCH_PNX4008 && I2C
Fix by dropping I2C from the above dependency; logic is that this is not a platform dependency but a configuration dependency: the _architecture_ still supports USB even is I2C is not selected.

which can be fixed by having MFD_TC6393XB select GPIOLIB instead of depending on it.
Signed-off-by: Guenter Roeck linux@roeck-us.net --- The USB build problem causes 15-20% of my randconfig builds to fail (6 of 36 failures last night).
I'll be happy to split the patch into three if it helps to get it accepted.
