When user gives us a block address to get its ID to mmap it, he also
needs to get from us the block size to pass to the driver in the mmap
function.

Currently this API uses single 64 bits mask for engines idle indication.
Recently, it was observed that more bits are needed for some ASICs.
This patch modifies the use of the idle mask and the idle_extensions
mask.

Up until now validation errors were counted in the parsing field
of the cs_counters struct, so we added a new counter and increased
it when needed.
In addition, there were some locations where only one of the counters
was updated (ctx or aggregate) so add the second one to be updated
as well.

In the future there will be situations where queues can accept either
kernel allocated CBs or user allocated CBs, depending on different
states.
Therefore, instead of using a boolean variable of kernel/user allocated
CB, we need to use a bitmask to indicate that, which will allow to
combine the two options.
Add a flag to the uapi so the user will be able to indicate whether
the CB was allocated by kernel or by user. Of course the driver
validates that.

There are cases in which the device should access the host memory of a
CB through the device MMU, and thus this memory should be mapped.
The patch adds a flag to the CB IOCTL, in which a user can ask the
driver to perform the mapping when creating a CB.
The mapping is allowed only if a dedicated VA range was allocated for
the specific ASIC.

The user sometimes wants to check if a CS has completed to clean resources.
In that case, the user doesn't want to sleep but just to check if the CS
has finished and continue with his code.
Add a new definition to the API of the wait on CS. The new definition says
that if the timeout is 0, the driver won't sleep at all but return
immediately after checking if the CS has finished.

ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.
Most of this change is an internal renaming of variables, functions and
defines but there are two entries in sysfs which have armcp in their
names. Add identical cpucp entries but don't remove yet the armcp entries.
Those will be deprecated next year. Add the documentation about it in sysfs
documentation.
