Jon Medhurst 1c1507d4cd i2c: i2c_sbcon: Driver for ARM's SBCon 2-wire serial interface
SBCon is a simple device which allows directly setting and getting the
hardware state of two-bit serial interfaces like I2C. Therefore to be
useable we need to drive the lines with the appropriate protocol under
software control.

Kumar Gala cc334c7273 Convert remaining code to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies.  We also convert the PRI printf formatters in the arch

Kumar Gala 789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Enable arc to access the i2c controller on I/O fabric.

X86 cpu is only able to access the i2c controller on the I/O

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 i2c_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

needed:

- QM_SCSS_INT is renamed to QM_INTERRUPT_ROUTER;
- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.
