Add additional status flags to UsbDataStatus

Browse Source 
This change introduces two new values to UsbDataStatus interface
to denote status of Usb data. Previously, UsbDataStatus interface
contained DISABLED_DOCK which indicated that USB data is disabled
due to a docking event. Depending on the hardware design, some
architectures might only disable USB host mode or USB gadget
mode selectively when docked. This change adds interface values
to denote them. DISABLED_DOCK_HOST_MODE indicates USB host mode
disabled due to docking event. DISABLED_DOCK_DEVICE_MODE indicates
device mode disabled due to docking event. DISABLED_DOCK needs to
be set when either of DISABLED_DOCK_HOST_MODE or
DISABLED_DOCK_DEVICE_MODE is set.
