From: Hilda Wu <hildawu@xxxxxxxxxxx>
This patch adds a data structure for btrealtek object, and the
definition of vendor behavior flags. It also adds macros to set/test/get
the flags.
Signed-off-by: Hilda Wu <hildawu@xxxxxxxxxxx>

Changes in v4:
- Since the original 0002 patch has no dependency with this 0001 patch.
So let the 0002 patch submit another.
Changes in v3:
- Update private flag.
Changes in v2:
- Set the proper priv_size to hci_alloc_dev_priv().
- Separate commits for functions.
