I’d like to extract timer API from current implementation.
And to make code more readable I’d like to introduce 'struct rk_timer’ what can be
reused with current implementation and with my patch (8/8). And in order keep patches
simple and readable I split that into three patches: 5/8, 6/8, 7/8.

Current implementation named rockchip timer as ‘struct bc_timer’ (broadcast timer).
I renamed it to more suitable to it role (may be bad choice).

Yes, the patch itself looks strange. You are right.

What do you think about that solution:
- in the patch 6/8 i will Introduce 'struct rk_timer’ and 'struct rk_time_clkevt’ (renamed ‘struct bc_timer’).
- rk_timer_init() changes from 5/8 I will merge with 8/8
- 8/8 introduce 'struct rk_time_clksrc' 
- 5/8 drop

Alexander.
