[PATCH v2 8/9] rtlwifi: btcoex: Add struct members to replace global varaibles

[pkshih]

From: Ping-Ke Shih <pkshih@xxxxxxxxxxx>

Chip specific context plays as global variables that will not support
multiple devices simultaneously. This patch adds 'union' fields to hold
the variables, and next patch will remove all of them.

To use the declaration of fields in halbtcoutsrc.h, I move the including
order in header file halbt_precomp.h, and declare two struct terms for
chip specific header files.
