As a first step to have a clearer separation of the different parts of
the kernel driver, the source files have been placed into separate
directories according to their purpose and the different parts are only
allowed to use headers from another part in the include folder.
Files have been renamed accordingly to namespace them by their purpose.

Changed several logs level from info to dbg and removed redundant or
uninformative logging in order to reduce verbosity of the kernel
modules.

When the kernel driver handles incoming rpmsg messages, it uses the ID
in the message header to find the corresponding mailbox message. The
mailbox messages are stored as a generic message struct that is later
cast to the specific message type.
There is currently no type information stored in the generic message
struct so only the ID is used to distinguish between the mailbox
messages. This means if an incorrect ID is received that matches a
mailbox message with a different type, the kernel driver will cast the
message struct to the wrong type.
Type information has now been added to the generic message struct and
will be checked when trying to find the corresponding mailbox message so
both the ID and type must be correct to find a matching message.

The 'struct ethosu_device' has been passed as argument to classes.
This creates a circular dependency dependency and it gives all
classes full visibility to all resources in the device struct. This
patch removes the circular dependency.
Using device_lock() and device_unlock() to for synchronization.

The Ethos-U kernel driver has been converted from a
platform driver with a custom firmware interface into a
rpmsg driver.

Avoid to use pointers to kernel memory as identify messages, prior this
change, if memory is reused that can lead to unexpected conflicts.
Remove ref counting from capabilities and network_info since memory is
freed in only one place.
Finally, extract the capabilities code in its own files.
