drivers: spi_shim: grant arc the access to spi on I/O fabric

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
