Return ENOTTY instead of ENOIOCTLCMD in user-visible ioctl() results

The watchdog drivers used to return ENOIOCTLCMD for bad ioctl() commands.
ENOIOCTLCMD should not be visible by the user, so use ENOTTY instead.

Mark the static struct file_operations in drivers/char as const.  Making
them const prevents accidental bugs, and moves them to the .rodata section
so that they no longer do any false sharing; in addition with the proper
debug option they are then protected against corruption..

In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON.  The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.

I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.
