The function i2c_dw_isr() in this file appears to have the wrong
decl for the IRQ_CONNECT macro. It should be: void i2c_dw_isr(void *arg).
Also, at the 2nd use of IRQ_CONNECT there was a variable created
and then marked as UNUSED. I've removed this.

Note that the failure case can only be reached when PCI is enabled.
Otherwise, the if-block is always false, which reduces code size
for non-PCI platforms.

The interrupt API has been redesigned:
- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
It will be used in situations where the new static irq_connect()
won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
exactly the same way as its dynamic counterpart. The old static irq
macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
generated inline with irq_connect()
ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

Make the i2c_transfer() to transact messages through the I2C bus.
It is useful for I2C storage devices, as now we can send one message
containing the destination byte/block address, then send the data
in another message. There is no need to construct one continuous
data buffer to send both address and data anymore.
The drivers and sample apps have been updated to utilize updated
API when appropriate. For i2c_dw, only master mode has been updated.
Slave mode will be updated once we can adequately test it.

Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.
The change in API means that device drivers and sample
applications need to use the new API.
IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()
