Initial import of Synopsis DesignWare I2C driver functionality
for the Zephyr Project. This import has been tested for host
master control. While it does contain the code to work as a host
slave, this code has not yet been completely tested and validated.

No need to keep track of PCI class's bus and dev. First, there might be
more than 1 bus and/or 1 device which would hold the same class.
Secondly, with the new PCI_ENUMERATION option, enumeration PCI device is
now optional and it's advised to unset such option and statically
configure the PCI information of the devices (to gain in booting time
and code size). So finally removing all of this.

- Finally switched from ldw/stw to ldh/sth, as Benjamin noticed in an
earlier comment (I was using ARC ISA, and not ARC V2 ISA). So indeed
ldw/stw are obsolete and equivalent to ldh/std.
- clear, set and test were not working in case of using a memory address
which would not point to a register: bclr, bset and btst requires
registers as operands, and cannot deal with pure memory address (i.e.
something like [rx] is not valid), thus the requirement to load first
the value pointed by the address into a register, operate on that
register and storing the result of it into the pointed address.

The event portion of the app_kernel benchmark no longer outputs the following
(abbreviated) error message:
<path to project>/app_kernel/src/event_b.c:86 Error: tick occurred
This error was occurring as the benchmark test had hard-coded the value of
the event TEST_EVENT to 0 instead of defining it in the prj.mdef file.
Consequently, the system was using event 0 for the tick event; every time
task_event_send(TEST_EVENT) was invoked, the system treated it as a tick event.

The profiler now uses the generic ring buffer. The dropped event
count is stored in the ring buffer's value field. The data size only
refers to the extra data attached to the message and NOT any internal
representation of metadata inside the ring buffer, the event_logger
APIs now pass this information along in dedicated parameters.

This patch is based on some code contributed by Dirk Brandewie.
This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.
Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.

Renames the document to better reflect its true nature -- it is
a reference guide that provides information about existing platform
configurations, not a "how to" that provides information about
creating a new platform configuration.
Re-orders the platform configuration entries so that they appear
in alphabetical order, and moves the links to the individual
platform configuration sections to the end. This allows a reader
to use the table to identify a platform configuration of interest,
then click on the link that follows to obtain more details.
Note: It would be ideal if the link to a specific platform configuration
section could be embedded in the associated table entry, but the :ref:
tag doesn't seem to allow this.
