drm: rename drm_fops.c to drm_file.c

It's not just file ops, but drm_file stuff in general. This is prep
work to extracting a drm_file.h header in the next patch.

-/**
- * DOC: file operations
- *
- * Drivers must define the file operations structure that forms the DRM
- * userspace API entry point, even though most of those operations are
- * implemented in the DRM core. The mandatory functions are drm_open(),
- * drm_read(), drm_ioctl() and drm_compat_ioctl() if CONFIG_COMPAT is enabled
- * (note that drm_compat_ioctl will be NULL if CONFIG_COMPAT=n). Drivers which
- * implement private ioctls that require 32/64 bit compatibility support must
- * provide their own .compat_ioctl() handler that processes private ioctls and
- * calls drm_compat_ioctl() for core ioctls.
- *
- * In addition drm_read() and drm_poll() provide support for DRM events. DRM
- * events are a generic and extensible means to send asynchronous events to
- * userspace through the file descriptor. They are used to send vblank event and
- * page flip completions by the KMS API. But drivers can also use it for their
- * own needs, e.g. to signal completion of rendering.
- *
- * The memory mapping implementation will vary depending on how the driver
- * manages memory. Legacy drivers will use the deprecated drm_legacy_mmap()
- * function, modern drivers should use one of the provided memory-manager
- * specific implementations. For GEM-based drivers this is drm_gem_mmap().
- *
- * No other file operations are supported by the DRM userspace API. Overall the
- * following is an example #file_operations structure::
- *
- *     static const example_drm_fops = {
- *             .owner = THIS_MODULE,
- *             .open = drm_open,
- *             .release = drm_release,
- *             .unlocked_ioctl = drm_ioctl,
- *             .compat_ioctl = drm_compat_ioctl, // NULL if CONFIG_COMPAT=n
- *             .poll = drm_poll,
- *             .read = drm_read,
- *             .llseek = no_llseek,
- *             .mmap = drm_gem_mmap,
- *     };
