On Quark SE, SPI might require GPIO to be ready before hand, to emulate
CS, thus providing an option to tweak the intialization priority for SPI
DW driver.

It might be necessary to emulate CS through a GPIO pin depending on
these 2 conditions:
- the controller's CS pin is not wired, and thus a GPIO pin is the only
option
- The controller is unstable at a certain frequency and cannot set/unset
CS reliably. This is actually a possible issue on DesignWare's SPI
controller in Quark SE or Quarks D2000 where it has been found
unstable at 1Mhz and above.

This patch introduces the QMSI I2C driver which is simply a shim driver
based on I2C driver provided by QMSI BSP.
This initial version supports only I2C_0 controller in 'master' mode.
Due to some issues with qm_i2c_master_irq_transfer API, the driver uses
the polling APIs from QMSI. This means that the current thread doesn't
sleep (i.e. is not scheduled out) while the I2C transfer is carried out.
The qm_i2c_master_irq_transfer() issue is under investigation.
Below follows the missing features which will be addressed by a new
version of this patch or by upcoming patches.
* Block the current thread until the I2C operation has actually
completed.
* Add support for multiple controllers.
* Add support for slave mode.
* Add support for suspend() and resume() APIs.
In order to enable this driver, the following options should be set:
CONFIG_QMSI_DRIVERS=y
CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory"
CONFIG_I2C=y
CONFIG_I2C_QMSI=y
Finally, due to the lack of proper support for Quark SE in QMSI 1.0.0,
this driver requires QMSI version greater than 1.0.0.
This driver has been tested only with Quark SE based boards.

Update the advertising API according to what has recently been
discussed and agreed upon.
Naming-wise the most important change is the removal of "EIR" which
was confusing since this is mainly used with LE at the moment. The
Core Specification Supplement consistently uses the generic terms data
and data type to describe what we're dealing with here, so the new
names are bt_data and BT_DATA.
Another change is to detach the actual data from the struct by
converting it from an array to a pointer. This is not only essential
for supporting BR/EDR (which has a different length) but to also
minimize memory usage.
Another change is to require the caller of bt_le_adv_start() to
provide the array lengths of the ad and sd paramters. This way we
don't have to have the empty (8-byte) element at the end of each
array.
Lastly, the bt_le_adv_start() logic is slightly modified so that it
will always clear the respective data if necessary. Previously the
user might have been left with a previous callers data if it passed
NULL to the API.

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.
