[PATCHv2 05/11] clocksource/drivers/rockchip_timer: split bc_timer into rk_timer and rk_clock_event_device

[Alexander Kochetkov]

The patch move ce field out of struct bc_timer into struct
rk_clock_event_device and rename struct bc_timer to struct rk_timer.

This is refactoring step without functional changes.
