The size computations done in the ioctl function use an integer.
If userspace submits a request with req->cmd_nr or req->cmd_buf_nr
set to INT_MAX, the integer computations overflow later, leading
to potential (kernel) memory corruption.

Prevent this issue by enforcing a limit on the number of submitted
commands, so that we have enough headroom later for the size
computations.

Note that this change has no impact on the currently available
users in userspace, like e.g. libdrm/exynos.

While at it, also make a comment about the size computation more
detailed.

We were trying to print an error message if we timed out here, but the
loop actually ends with "tries" set to UINT_MAX and not zero.  Fix this
by changing from tries-- to --tries.

A for loop would actually be the most natural way to do this.  My fix
means we only loop 99 times instead of 100 but that's probably ok.

This patch replaces specific atomic commit function
with atomic helper commit one.

For this, it removes existing atomic commit function
and relevant code specific to Exynos DRM and makes
atomic helper commit to be used instead.

Below are changes for the use of atomic helper commit:
- add atomic_commit_tail callback specific to Exynos DRM
  . default implemention of atomic helper doesn't mesh well
    with runtime PM so the device driver which supports runtime
    PM should call drm_atomic_helper_commit_modeset_enables function
    prior to drm_atomic_helper_commit_planes function call.
    atomic_commit_tail callback implements this call ordering.
- allow plane commit only in case that CRTC device is enabled.
  . for this, it calls atomic_helper_commit_planes function
    with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.

yet), we no longer need to put the fbdev creation code in
