Adding adaption/glue layer where the I2C host adapter
(Synopsys DesignWare I2C adapter) and the I2C clients (the
microcontroller units) are enumerated.
The microcontroller units (MCU) that are attached to the GPU
depend on the OEM. The initially supported MCU will be the
Add-In Management Controller (AMC).

When something happen to the session, the HW generates a termination
interrupt. In reply to this, the driver is required to submit an inline
session termination via the VCS, trigger the global termination and
notify the GSC FW that the session is now invalid.

IRQ registers have a well-defined scope and make sense to collect in a
dedicated header file. This also reduces confusion about the GT IRQ
registers --- even though those registers relate to the GTs, they
actually live outside the GT (in the sgunit) and thus do not need to
worry about GT-specific register concepts like forcewake, steering, etc.
