Most of our helpers have relied on being selected so far through
Kconfig, but that creates issues when we have multiple layers of helpers
with some depending on others.

Indeed, select doesn't select a dependency's dependencies, and thus
isn't super intuitive. Depends on however doesn't have that limitation,
so we can just switch all the drivers that were selecting
DRM_DISPLAY_HELPER to depend on it.

While most display helpers Kconfig symbols have the DRM_DISPLAY prefix,
the DisplayPort AUX bus implementation uses DRM_DP_AUX_BUS.

Since the number of users is limited and it's a selected symbol, we can
easily rename it to make it consistent.

The init sequence specifies the 0x11 and 0x29 dsi commands, which are
the exit-sleep and display-on commands.

In the actual prepare step the driver already uses the appropriate
function calls for those, so drop the duplicates.

If an eDP panel is not powered on then any attempts to talk to it over
the DP AUX channel will timeout. Unfortunately these attempts may be
quite slow. Userspace can initiate these attempts either via a
/dev/drm_dp_auxN device or via the created i2c device.

Making the DP AUX drivers timeout faster is a difficult proposition.
In theory we could just poll the panel's HPD line in the AUX transfer
function and immediately return an error there. However, this is
easier said than done. For one thing, there's no hard requirement to
hook the HPD line up for eDP panels and it's OK to just delay a fixed
amount. For another thing, the HPD line may not be fast to probe. On
parade-ps8640 we need to wait for the bridge chip's firmware to boot
before we can get the HPD line and this is a slow process.

The fact that the transfers are taking so long to timeout is causing
real problems. The open source fwupd daemon sometimes scans DP busses
looking for devices whose firmware need updating. If it happens to
scan while a panel is turned off this scan can take a long time. The
fwupd daemon could try to be smarter and only scan when eDP panels are
turned on, but we can also improve the behavior in the kernel.

Let's let eDP panels drivers specify that a panel is turned off and
then modify the common AUX transfer code not to attempt a transfer in
this case.

As with several other panel drivers, this fails to link without the DP
helper library:

ld: drivers/gpu/drm/panel/panel-raydium-rm692e5.o: in function `rm692e5_prepare':
panel-raydium-rm692e5.c:(.text+0x11f4): undefined reference to `drm_dsc_pps_payload_pack'

Select the same symbols that the others already use.

It turns out that I had misconfigured the device I was using the panel
with; the bus data polarity is not high for this panel, I had to change
the config on the display controller's side.

Fix the panel config to properly reflect its accurate settings.

At least the pixelclock has a range which can vary. Convert fixed mode
into display timings so they can be overwritten in DT if necessary.
