patch adds the necessary configuration to handle also display capture
mode.
We need to set CAPTUREMODE to 0 (continuous capture), and WBDELAYCOUNT
according to the vertical timings of the display, so that the WB FIFO

When a new cooling device is registered, we need to update the
thermal zone to set the new registered cooling device to a proper
state.
This fixes a problem that the system is cool, while the fan devices
are left running on full speed after boot, if fan device is registered
after thermal zone device.
Here is the history of why current patch looks like this:

Current thermal code does not handle system sleep well because
1. the cooling device cooling state may be changed during suspend
2. the previous temperature reading becomes invalid after resumed because
it is got before system sleep
3. updating thermal zone device during suspending/resuming
is wrong because some devices may have already been suspended
or may have not been resumed.
Thus, the proper way to do this is to cancel all thermal zone
device update requirements during suspend/resume, and after all
the devices have been resumed, reset and update every registered
thermal zone devices.
This also fixes a regression introduced by:
Commit 19593a1fb1 ("ACPI / fan: convert to platform driver")
Because, with above commit applied, all the fan devices are attached
to the acpi_general_pm_domain, and they are turned on by the pm_domain
automatically after resume, without the awareness of thermal core.

After thermal zone device registered, as we have not read any
temperature before, thus tz->temperature should not be 0,
which actually means 0C, and thermal trend is not available.
In this case, we need specially handling for the first
thermal_zone_device_update().
Both thermal core framework and step_wise governor is
enhanced to handle this. And since the step_wise governor
is the only one that uses trends, so it's the only thermal
governor that needs to be updated.

Donald Buczek reports that NFS clients can also report incorrect
results for access() due to lack of revalidation of attributes
before calling execute_ok().
Looking closely, it seems chdir() is afflicted with the same problem.
Fix is to ensure we call nfs_revalidate_inode_rcu() or
nfs_revalidate_inode() as appropriate before deciding to trust
execute_ok().

DWC3 device found on Exynos SoCs cannot work in OTG mode alone, because
it lacks some OTG related control part. OTG mode operation is possible
only with external hardware logic (usually GPIO-based) specific to
the board. Right now, however, there is no driver for such logic and no
bindings, so the OTG mode is dysfunctional at all (this means that it
doesn't work as a peripheral nor as a host). This patch sets the operation
mode to peripheral to get DWC3_1 device at least somehow working. This can
be later updated, when proper OTG driver and bindings get developed.
