The flash memory in arduino 101 pĺatform is connected to the
SPI MST 0 device and the CS is connected to the GPIO 0.
The arduino 101 sensor sub-system core maps the SPI MST 0 device
to the "SPI_2" name and the SPI SS 0 device to the "SPI_0" name.
In the same manner the GPIO 0 is mapped to the "GPIO_2" name and
the GPIO SS 0 is mapped to the "GPIO_0" name.
This commit fixes the SPI device name and the GPIO name used by
the W25QXXDV flash memory.

Enable arc to access the spi controller on I/O fabric.
There are two spi controllers on quark se SoC. One is attached
to the I/O fabric and the other one is in the sensor system.
X86 cpu is only able to access the spi controller on the I/O
fabric and the access is supported by existing code. HW allows
arc to access both controllers. But, the existing code only
gives arc access to the controller in the sensor sub-system.
Let's grant arc the access to the controller on I/O fabric as
well by the following changes.
1. Add spi_qmsi.c into arc compilation.
2. Use the already defined macros to choose interrupt numbers
and do interrupt unmasking automatically based on the
compilation targets.
3. Add new symbols in Kconfig including driver names for both
controllers

Introduce an architecture sorting of boards. This is to allow for
easier maintenance going forward as the number of boards grows. It
will be easier for any scripts to know the board/arch mapping without
having to maintain an explicit list of what boards are associated with
which arch. We can also do things like have architecture maintainers
cover reviews and branches for arch/${ARCH} and boards/${ARCH} going
forward.
