No reason to hide the pipe CRC code inside the debugfs stuff.
The fact that pipe CRCs are operated through debugfs is just
an irrelevant implementation detail.

Fixed up the few cases that don't include igt.h with this cocci:
@find@
identifier ID;
@@
igt_crc_t ID;

@has_include@
@@
(
 #include "igt_pipe_crc.h"
|
 #include "igt.h"
)

@depends on find && !has_include@
@@
  #include "igt_kms.h"
+ #include "igt_pipe_crc.h"

v2: better cocci to catch lib/igt_chamelium.c
v3: Rebase and roll on doc fix from Petri
v4: Use SPDX stuff
