Daniel Leung a0a140f470 uart/nsim: Make config for uart/nsim explicit
This adds CONFIG_UART_NSIM to enable the uart/nsim driver.
This fixes compilation issue where the base address parameter
is not defined due to CONFIG_NSIM=y but CONFIG_SERIAL=n.

Since all the necessary bits utilizing UART by index have moved to
use device name instead, the uart_devs[] can finally be removed.

Daniel Leung 1d816afcc0 serial: remove unused code after refactoring
Remove unused code after refactoring all the serial/UART drivers.

() Since device initialization is done by the drivers themselves,
   there is no need to have config_func(), port_init() and uart_init()
   to perform configuration external to driver. So remove the related
   bits.
() The IRQ priority is only being used when doing IRQ_CONNECT_STATIC().
   So there is no need to send it over during uart_init().

Peter Mitsis 5c39418ae8 k20uart: Fix check for Rx/Tx irq
Due to a quirk of the k20 UART, when checking if either a Tx or Rx
irq is ready, one must first check whether the UART has enabled the
Tx and/or Rx interrupts.  If this is not done, then all one is doing
is testing the UART to determine if it is ready to Tx and/or Rx.

Daniel Leung 2fd29e2667 serial: converting to new driver initialization model
This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.

Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.

Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

Dmitriy Korovkin 660878e4e2 irq_connect for x86 uses static stub array
In order to provide the same irq_connect() on all platforms
on x86, irq_connect() now uses a static array of interrupt
stubs. Device driver does not need to provide interrupt stub
to irq_connect() function.

Add NUM_DYNAMIC_STUBS configuration parameter, the number
of interrupt stubs used for dynamic interrupt registration.

Modify tests for unified interrupt register API

Tests that deal with interrupts are modified to work
with the new interrupt registration API.

Add CONFIG_NUM_DYNAMIC_STUBS option to dynamic interrupt projects

Projects that use dynamic interrupt handler registration on x86
have to include CONFIG_NUM_DYNAMIC_STUBS parameter in the
configuration.
