Wentao Guan 5eb070769e USB: cdc-acm: Fix bit overlap and move quirk definitions to header

The VENDOR_CLASS_DATA_IFACE and ALWAYS_POLL_CTRL quirk flags added in
commit f58752ebcb ("USB: cdc-acm: Add quirks for Yoga Book 9 14IAH10
INGENIC touchscreen") were placed inside the acm_ctrl_msg() function
rather than in the header with the other quirk flags.  Then, their
values (BIT(9) and BIT(10)) collided with NO_UNION_12 which is already
BIT(9).

Move the definitions to drivers/usb/class/cdc-acm.h where they belong
and shift them to BIT(10) and BIT(11) to avoid the overlap.
