drm/i915: Reduce duplicated forcewake logic

Introduce a structure to track the individual forcewake domains and use
that to eliminate duplicate logic.

v2: - Rebase on latest dinq (Mika)
    - for_each_fw_domain macro (Mika)
    - Handle reset atomically, keeping the timer running (Mika)
    - for_each_fw_domain parameter ordering (Chris)
    - defer timer on new register access (Mika)

v3: - Fix forcewake_reset/get race by waiting pending timers

v4: - cond_resched and verbose warning on timer deletion (Chris)
    - need to run pending timers manually on reset
