To many people, IPI connotes inter-processor interrupts on SMP
systems. Rename this to IPM, or Inter-Processor Mailboxes.

Original name was too generic and confusing. This patch renames
driver to pipe UART and moves it to console drivers folder. Kconfig
destription is also improved.

Quark SE provides various clock controllers through its SCSS block.
Peripheral, external, sensor, and others.
This current drivers provides only the clock gating capability, for
peripheral, external and sensor. But it could support divider and more
other features once defined in the generic API.
Note: such clock has _nothing_ to do with a Real Time Clock (RTC).
An RTC provide clock timing like a watch would do. Here the clock
controller is about circuit clocking.

This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available. Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked. Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code. Another
simplification is that none of the offload capabilities of the
Ethernet device are used. The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.

This driver allows multiple drivers to share a common interrupt
line. This functionality is required on system that conform to the PC
interrupt structure. In the context of Zephyr this is needed for
SOC's that have their I/O IP blocks behind a PCI interface. Due to the
limited number of interrupt lines provided by the PCI interface
multiple IP blocks may be configured to share an interrupt line.
Drivers that share interrupts must be modified to *not* register their
own interrupt service routine as part of their configuration/initialization
but instead bind to the correct instance of this driver by name, then
register their interrupt service routine with this driver.

This driver is a very simple UART driver that can be used to implement
a protocol in application. It has no protocol logic and just allow
application to receive and send data over UART in platform independent
manner.
API is designed to minimize number of required memory copies.
Application is able to provide new buffer every time it decides to
consume received data. It is also able to just alter offset and
reuse current buffer eg if data was corrupted or otherwise invalid.
