This patch replaces all occurences of the macro DEV_INVALID_CONF by
-EINVAL at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.
Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.
This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.
Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.
This also addresses the following issues:
() UART driver for Atmel SAM3 currently does not support interrupts.
So remove the code from vector table. This will be updated when
there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.
This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

The data is in a net_buf already so we can just pass this to the
deserialization code. The net_buf context and API helps simplify the
code quite a lot.

Don't require being able to read the full header in a single ISR call.
Instead track the number of received header bytes. Also check for IPC
length before allocating buffer to avoid unnecessary buffer
allocations.

We can take advantage of the net_buf headroom. At the same time move
the necessary definition straight into uart.c and remove any unused
definitions.

Using net_buf helps us remove a lot of the pointer & data length
book-keeping variables and in general makes the code more readable.

With peripheral application there is at least 6 commands sent in a row
which will lead to 6 responses which might cause the driver to run out
of buffers so this increases it to 8 to align with HCI driver.

Since application callbacks happen from the rx thread we cannot have
the stack as small as just 256 bytes. Make it 2kB for now, but later
this needs to be adjusted to some reasonable minimum with the help of
the stack analysis code, and then probably accompanied by a Kconfig
option for apps to increase if if needed.

uart driver and all data is sent there for processing. Clean up old
