staging: r8822be: Add r8822be btcoexist routines to staging

The RTL8822BE, an 802.11ac wireless network card, is now appearing in new computers. Its driver is being placed in staging to reduce the time that users of this new card will have access to in-kernel drivers. This commit adds the routines needed for BT coexistence with the new driver.
