The locking in the acx565akm panel driver was getting too complex. Clean
it up by making new functions, acx565akm_bl_get_intensity_locked and
acx565akm_bl_update_status_locked, which are called by the backlight
subsystem. This way the non-locked versions can be called by the panel's
other funcs, simplifying the lock management.

When booting Nokia N900 smartphone with v3.12 + omap2plus_defconfig
(LOCKDEP enabled) and CONFIG_DISPLAY_PANEL_SONY_ACX565AKM enabled,
the following BUG is seen during the boot:

[    7.302154] =====================================
[    7.307128] [ BUG: bad unlock balance detected! ]
[    7.312103] 3.12.0-los.git-2093492-00120-g5e01dc7b #3 Not tainted
[    7.318450] -------------------------------------
[    7.323425] kworker/u2:1/12 is trying to release lock (&ddata->mutex) at:
[    7.330657] [<c031b760>] acx565akm_enable+0x12c/0x18c
[    7.335998] but there are no more locks to release!

Fix by removing double unlock and handling the locking completely inside
acx565akm_panel_power_on() when doing the power on.

While using HDMI connector driver with sil9022 encoder
came across issue where connector driver is probed first.
This resulted in error. A deffered probe solved this.
Most connector drivers need a encoder driver as their
video source. This patch ensures we do a probe defferal
if video source is not present for connector drivers.

In the old panel device model we had omap_dss_output entities,
representing the encoders in the DSS block. This entity had "device"
field, which pointed to the panel that was using the omap_dss_output.

With the new panel device model, the omap_dss_output is integrated into
omap_dss_device, which now represents a "display entity". Thus the "device"
field, now in omap_dss_device, points to the next entity in the display
entity-chain.

This patch renames the "device" field to "dst", which much better tells
what the field points to.

In the old panel device model we had "outputs", which were the encoders
inside OMAP DSS block, and panel devices (omap_dss_device). The panel
devices had a reference to the source of the video data, i.e. reference
to an "output", in a field named "output".

That was somewhat confusing even in the old panel device model, but even
more so with the panel device model where we can have longer chains of
display entities.

This patch renames the "output" field to "src", which much better tells
what the field points to.

connector-analog-tv.c uses omap_dss_pal_timings, defined in omapdss's
venc.c, for default timings. omap_dss_pal_timings only exists when VENC
is enabled in the kernel config, so disabling VENC breaks
omap_dss_pal_timings connector-analog-tv compilation.

Instead of adding dependency to VENC, add internal default timings to
the connector driver, because the connector driver should not depend on
VENC, and it can be used with any other analog TV encoder.
