1e5866711a i2c: thunderx: Add SMBUS alert support 
Add SMBUS alert interrupt support. For now only device tree is
supported for specifying the alert. In case of ACPI an error
is returned.

22d40209de i2c: thunderx: Add i2c driver for ThunderX SOC 
The ThunderX SOC uses the same i2c block as the Octeon SOC.
The main difference is that on ThunderX the device is a PCI device
so device probing is done via PCI, interrupts are MSI-X. The
clock rates can be set via device tree or ACPI.
