Valdis Klētnieks 0a54b809a3 RAS: Fix prototype warnings
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. ]
