drm/tegra: dpaux: Fix PM disable depth imbalance in tegra_dpaux_probe
The pm_runtime_enable function increases the power disable depth,

Additionally, we need to address the same issue for pm_runtime_get_sync.
We fix this by invoking pm_runtime_disable and pm_runtime_put_sync

The rough consensus is that no helper or extra scaffolding is needed

At least for now. Other drivers that currently do long-running workloads
have no plat to use drm-scheduler. Besides, the current consensus is
that this solution of simply returning NULL to the run_job function should
work without extra code duplication or complication.

so let's move that to the 'Completed' section and revisit the long-running

After reading the code, I think this is what happens:
We have a DSI host defined in the device tree and a DSI peripheral under
that host (i.e. an i2c device using the DSI as data bus doesn't exhibit
this behavior).
The host driver calls mipi_dsi_host_register(), which causes (via a few
functions) mipi_dsi_device_add() to be called for the DSI peripheral. So
now we have a DSI device under the host, but attach hasn't been called.
Normally the probing of the devices continues, and eventually the DSI
peripheral's driver will call mipi_dsi_attach(), attaching the
peripheral.
However, if the host driver's probe encounters an error after calling
mipi_dsi_host_register(), and before the peripheral has called
mipi_dsi_attach(), the host driver will do cleanups and return an error
from its probe function. The cleanups include calling
mipi_dsi_host_unregister().
mipi_dsi_host_unregister() will call two functions for all its DSI
peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister().
The latter makes sense, as the device exists, but the former may be
wrong as attach has not necessarily been done.
To fix this, track the attached state of the peripheral, and only detach
from mipi_dsi_host_unregister() if the peripheral was attached.
Note that I have only tested this with a board with an i2c DSI
peripheral, not with a "pure" DSI peripheral.
However, slightly related, the unregister machinery still seems broken.
E.g. if the DSI host driver is unbound, it'll detach and unregister the
DSI peripherals. After that, when the DSI peripheral driver unbound
it'll call detach either directly or using the devm variant, leading to
a crash. And probably the driver will crash if it happens, for some
reason, to try to send a message via the DSI bus.
