arm64: dts: Remove bootargs from chosen node

The shim layer and cboot shall append to the kernel command line
present in the /chosen/bootargs.

Right now, cboot overwrites to this property anyway, to avoid conflicts.
Hence, we should be good to remove chosen/bootargs. This is done to be able to
add a property to command line easily, through the top level DTS, if needed,
later on.

gpu: nvgpu: gm20b: Require rework for DVFS and rg

Boards require a rework to make railgating and DVFS work realiably.
The information whether the board has been reworked or not will be
available on DTS.

This patch adds a DTS check to the GPU driver initialisation. If the
rework information is not available (or the rework has been marked as
disabled), railgating and DVFS are disabled.

asoc: codec: audience: Don't clear cachedcmd_list

Don't clear cachedcmd_list from Algorithm kcontrol

The cachedcmd_list now holds the refcount information for each MUX which
is set twice. If it is cleared from the Algorithm kcontrol when it is
set to Off, it would erase the refcount information as well which is
required to update the power state of DAPM widgets when refcount reaches
to zero.

Added an extra check for skipping the power state update for DAPM
widget. In case of dragon board XML, if the playback is running and the
capture is started via Sound Recorder app, the MUXes are not set twice
as they are already set. But the disable sequence of playback gets
executed. In this case, the refcount of all the MUXes would be
decremented in disable sequence, and that would break the DAPM route
even if the TX (capture) stream is still active. The extra check of
active streams before updating the power state of DAPM widget will keep
the DAPM route as it is.
