This was failing, the documentationg provides numbers only telling at
one places these are hexadecimal values. So switching to hexadecimal.
Then DDS rate retrieving macro was bogus, so fixing it.
And adding debug output about the DDS rate and the clock ratio.

Add Kconfig option to specify how interrupt is triggered for SPI.
Also enabling such support for Galileo platform.

This is specific to Galileo board where its SPI port 0 needs to setup
the CS pin through a GPIO pin.

There are devices that need are part of the architecture core the need
to be initialized prior to devices that are integrated around a core
to make up a complete SOC. Namely the interrupt controller in the SOC
must be configured in order to allow the integrated IP blocks drivers
to initialize correctly.

This macro is legacy from an early implementation of the init system
before the pure level was split into early and late phases remove it
now to avoid confusion going forward.

The code fragment to bind the instances of the SPI driveri is not
platform specific but is driver specific.
All the information required to bind a driver instance comes from
CONFIG_ variables. Having the binding code with the driver code
avoids duplicating the code fragments in each platform where the
driver may be used.

Or then the controller will spin around requesting to get its fifo
filled-in though it's unnecessary.

- Handle the new error callback type, a ROR interrupt is irrecoverable.
- Removing the fifo pre-fill: this should never be done that way. It's
up to the controller to request via an interrupt to get its fifo
filled-in. (TFS bit on SSSR register is the one requesting such
filling)
- Disabling the controller once completed (following transfer will
re-enable it)
- Removing useless debugging info

Without it, it won't go through a pci scan, and will just trust the
pre-set information for the bus/dev/function to enable the memory
mapped registers.

Such controllers are found in Quark's X1000 series, and thus are found
on Galileo boards v1 and v2.
