intel: common: print out all dword with field spanning multiple dwords

For example, we were skipping Dword 3 in this PIPE_CONTROL :

0x000ce130:  0x7a000004:  PIPE_CONTROL
    DWord Length: 4
0x000ce134:  0x00000010 : Dword 1
    Flush LLC: false
    Destination Address Type: 0 (PPGTT)
    LRI Post Sync Operation: 0 (No LRI Operation)
    Store Data Index: 0
    Command Streamer Stall Enable: false
    Global Snapshot Count Reset: false
    TLB Invalidate: false
    Generic Media State Clear: false
    Post Sync Operation: 0 (No Write)
    Depth Stall Enable: false
    Render Target Cache Flush Enable: false
    Instruction Cache Invalidate Enable: false
    Texture Cache Invalidation Enable: false
    Indirect State Pointers Disable: false
    Notify Enable: false
    Pipe Control Flush Enable: false
    DC Flush Enable: false
    VF Cache Invalidation Enable: true
    Constant Cache Invalidation Enable: false
    State Cache Invalidation Enable: false
    Stall At Pixel Scoreboard: false
    Depth Cache Flush Enable: false
0x000ce138:  0x00000000 : Dword 2
    Address: 0x00000000
0x000ce140:  0x00000000 : Dword 4
    Immediate Data: 0
