When building with C=2 and/or W=1, legitimate warnings are issued about
missing prototypes:
CHECK drivers/ras/debugfs.c
drivers/ras/debugfs.c:4:15: warning: symbol 'ras_debugfs_dir' was not declared. Should it be static?
drivers/ras/debugfs.c:8:5: warning: symbol 'ras_userspace_consumers' was not declared. Should it be static?
drivers/ras/debugfs.c:38:12: warning: symbol 'ras_add_daemon_trace' was not declared. Should it be static?
drivers/ras/debugfs.c:54:13: warning: symbol 'ras_debugfs_init' was not declared. Should it be static?
CC drivers/ras/debugfs.o
drivers/ras/debugfs.c:8:5: warning: no previous prototype for 'ras_userspace_consumers' [-Wmissing-prototypes]
8 | int ras_userspace_consumers(void)
| ^~~~~~~~~~~~~~~~~~~~~~~
drivers/ras/debugfs.c:38:12: warning: no previous prototype for 'ras_add_daemon_trace' [-Wmissing-prototypes]
38 | int __init ras_add_daemon_trace(void)

drivers/ras/debugfs.c:54:13: warning: no previous prototype for 'ras_debugfs_init' [-Wmissing-prototypes]
54 | void __init ras_debugfs_init(void)

Provide the proper includes.
[ bp: Take care of the same warnings for cec.c too. ]
