dt-bindings: usb: dwc3: add dis-u1u2-quirk

Browse Source 
This patch adds a quirk for some special platforms (e.g.
rk1808 platform) which has problem to exit to U0 state
from U1 or U2 state when dwc3 work as peripheral mode.
To workaround this issue, we can add this quirk to reject
transition to U1 and U2 state.
