intel: gen-decoder: don't decode fields beyond a dword length
For example, a PIPE_CONTROL with DWordLength = 2 should look like
this :
0xffffe374: 0x7a000002: PIPE_CONTROL
0xffffe374: 0x7a000002 : Dword 0
DWord Length: 2
0xffffe378: 0x00800000 : Dword 1
Depth Cache Flush Enable: false
Stall At Pixel Scoreboard: false
State Cache Invalidation Enable: false
Constant Cache Invalidation Enable: false
VF Cache Invalidation Enable: false
DC Flush Enable: false
Pipe Control Flush Enable: false
Notify Enable: false
Indirect State Pointers Disable: false
Texture Cache Invalidation Enable: false
Instruction Cache Invalidate Enable: false
Render Target Cache Flush Enable: false
Depth Stall Enable: false
Post Sync Operation: 0 (No Write)
Generic Media State Clear: false
TLB Invalidate: false
Global Snapshot Count Reset: false
Command Streamer Stall Enable: false
Store Data Index: 0
LRI Post Sync Operation: 1 (MMIO Write Immediate Data)
Destination Address Type: 0 (PPGTT)
Flush LLC: false
0xffffe37c: 0x00000000 : Dword 2
Address: 0x00000000
0xffffe384: 0x05000000: MI_BATCH_BUFFER_END
Prior to this change, fields beyond the length of the command would be
decoded (notice the MI_BATCH_BUFFER_END decoded as part of the
previous PIPE_CONTROL) :
0xffffe374: 0x7a000002: PIPE_CONTROL
0xffffe374: 0x7a000002 : Dword 0
DWord Length: 2
0xffffe378: 0x00800000 : Dword 1

0xffffe384: 0x05000000: MI_BATCH_BUFFER_END
