Restore page-flip support now that the atomic conversion is complete.

Since the mode parameter to vbox_crtc_set_base_and_mode() now never
is NULL call drm_atomic_crtc_needs_modeset() to check if we need to
check for input-mapping changes, to avoid doing unnecesarry work on
a flip. And hookup the drm_atomic_helper_page_flip helper to implement
the page_flip callback.

staging: vboxvideo: Atomic phase 3: Switch last bits over to atomic

Now that the state objects are wired up, we can:

1) Move to the final atomic handlers
2) Wire up atomic set_config helper
3) Switch to drm_mode_config_helper_suspend/resume for suspend/resume
4) Enable atomic modesetting ioctl

This is all done in one commit because doing this piecemeal leads to
an intermediate state which triggers WARN_ONs in the atomic code because
e.g. plane->fb is still being set.

staging: vboxvideo: Cache mode width, height and crtc panning in vbox_crtc

When setting a mode we not only pass the mode to the hypervisor,
but also information on how to map / translate input coordinates
for the emulated USB tablet.  This input-mapping may change when
the mode on *another* crtc changes.

This means that sometimes we must do a modeset on other crtc-s then
the one being changed to update the input-mapping. Including crtc-s
which may be disabled inside the guest (shown as a black window
on the host unless closed by the user).

With atomic modesetting the mode-info of disabled crtcs gets zeroed
yet we need it when updating the input-map to avoid resizing the
window as a side effect of a mode_set on another crtc.

This commit adds caching of the mode info into out private vbox_crtc
struct so that we always have the info at hand when we need it.

staging: vboxvideo: Temporarily remove page_flip support

drm_mode_page_flip_ioctl() cannot deal with the in between phase of
the transitioning to atomic modeset support. Once we start using
drm_helper_crtc_mode_set(), we start setting plane->state on the primary
plane. But we are not fully atomic yet so then set both plane-state->fb
and plane->fb.

If both plane-state->fb and plane->fb are set drm_mode_page_flip_ioctl()
gets confused and stops calling drm_framebuffer_get() on the new fb while
still calling drm_framebuffer_put() on the old fb.

The current page_flip implementation expects drm_mode_page_flip_ioctl()
to take care of both and once we switch to drm_atomic_helper_page_flip()
that will expect neither to be done, taking care of both itself.

So for the transition we need to remove page_flip support and then after
the transition is complete and we set DRIVER_ATOMIC in our driver_features,
we can start using drm_atomic_helper_page_flip().

staging: vboxvideo: Cleanup vbox_set_up_input_mapping()

This cleanups 2 things:

1) The first time we loop over the crtc-s, to compare framebuffers, fb1 may
get set to NULL by the fb1 = CRTC_FB(crtci); statement and then we call
to_vbox_framebuffer() on it. The result of this call is only used for
an address comparison, so we don't end up dereferencing the bad pointer,
but still it is better to not do this.

2) Since we already figure out the first crtc with a fb in the first loop
and store that in fb1, there is no need to loop over the crtc-s again just
to find the first crtc with a fb again.

staging: rtl8188eu: Simplify memcmp logical checks

Clang generates a warning when it sees a logical not followed by a
conditional operator like ==, >, or < because it thinks that the logical
not should be applied to the whole statement:

drivers/staging/rtl8188eu/core/rtw_ieee80211.c:293:8: warning: logical
not is only applied to the left hand side of this comparison
[-Wlogical-not-parentheses]

It assumes the author might have made a mistake in their logic:

if (!a == b) -> if (!(a == b))

Sometimes that is the case; other times, it's just a super convoluted
way of saying 'if (a)' when b = 0:

if (!1 == 0) -> if (0 == 0) -> if (true)

Alternatively:

if (!1 == 0) -> if (!!1) -> if (1)

Simplify these comparisons so that Clang doesn't complain.
