For controls that are dependent from others, we need to "cluster" them.
Whenever one or more controls of the same cluster are set or gotten,
only the callback of the 1st control of the cluster, i.e. the master
control, is called. The master control is the one that represents the
whole cluster.
A common type of control cluster is "auto"-cluster, e.g. auto_gain/gain,
auto_exposure/exposure, auto_white_balance/red_balance/blue_balance,
etc. If the cluster is in automatic mode, then the manual controls are
marked inactive and volatile which are read via get_volatile_ctrl().
If the cluster is put in manual mode, then the manual controls should
become active again and the volatile flag is cleared.
Re-implement the ov5640's autogain/analogue_gain controls with the new
auto cluster mechanism so that it work correctly and fully.

Add get_volatile_ctrl() driver's API to retrieve the current value of a
control marked as volatile, e.g. gain, exposure. This function triggers
a hardware register reading instead of returning a cached value to ensure
that users always get a fresh value which is constantly updated by the HW.
Note that the driver is responsible for marking a control as volatile by
setting VIDEO_CTRL_FLAG_VOLATILE when registering a control because not
all hardwares work the same way for the same control.

Application can query information about a control given the control id,

Implement the video control framework with the following features:
- Drivers initialize the control with a valid value range at boot which
guides the application developer and the framework. Hence, the video
framework could do all common works for drivers e.g., sanity check.
- Controls need to be cached to memory. Video framework handles
get_ctrl(), drivers don't need to implement this API. It is because
reading control value directly from registers are not only inefficient
but also sometimes impossible, e.g. controls that scatter through
several registers. Only "volatile" control needs to be updated at
runtime.
- Only the devices (e.g., sensors) owning the controls need to
implement set_ctrl(). Other devices of the pipeline do not need to
propagate set_ctrl() and hence, do not need to implement this API

Introduce a new video device structure representing a device in a
video pipeline. Each video device embeds a pointer to its "source"
device and other "video" characteristics.
This structure give the video framework an access to all video features
of the device and a hierachical view of the video pipeline that the
device belongs to.

The `nocache` is not loadable, thus data stored therein cannot be
initialized by the startup code. This might be needed in special
cases. E.g. One might have a buffer which one wants to DMA into,
and which is a member of a struct. Other members of the struct one
may want to have initialized by the startup code.
The buffer thus should be placed in the `nocache` region, but for
the other members of the buffer to be initialized by the startup
code, the `nocache` region needs to be loadable.
Fix it by making the `nocache` region loadable. Adding a KConfig
symbol to do this optionally was considered, but deemed unnecessary
during the PR.

The logic of clock initialization for i2c fast mode (FM) and fast
mode plus (FMP) is as follows:
1 compute how many system clock cycles for SCL to be low
2 compute how many system clock cycles for SCL to be high by
subtracting the low duration computed above from the SCL period
3 verify the high duration computed in 2 is larger than a minimum
The bug is that the step 3 for the FMP is compared with the
minimum value for FM, and causes it to fail.
The fix corrects the bug.

Intel Audio DSP ACE needs to use arch_spin_relax() to give
the bus more time to propagate the RCW transactions among
CPUs, and to avoid sending too many requests to the bus
after failing to lock spinlocks. However, the number of
NOPs results in a very big arch_spin_relax() that spans
multiple instruction cache lines, and requires evicting
them just for NOPs. With 5 CPUs, it can span 6 cache
lines (if using nop.n instead of nop). That's a waste of
space and cache. So instead, we do a tight loop instead.
Since the SoC supports zero-overhead loops, this should
have minimal performance impact.

For some weird unknown reasons, the simulator really do not
like the cpuhold_* variables to be tightly packed together.
This results in cpuhold_spawned not being updated, and we
will be stuck in the while loop for it to be set.
Workaround this by explicitly aligning these variables on
16 byte boundary. This seems to work for now.

When all states are locked or latency requirement cannot be met
by any power state it is important to be able to quickly exit
suspend procedure because that usually means that application
requires high performance. Add function for detecting if any
power state is available.
Additionally, add function pm_policy_state_is_available for
checking if given state is available which means that it is not
locked and fulfills current latency requirement.

In hardware, cva6 currently only provides global disable/enable
functions for the Dcache and Icache. Disabling and re-enabling them also
has the effect of flushing and invalidating the cache.
Future cva6 SoCs will add support RISC-V's standardized cache management
operations.
This commit provides a default implementation for all methods currently
part of the cache API. These implementations can be overwritten at board
or SoC level, as they use weak linking.
