so enable it to get a working network interface.

FWIW, the revert fixes the boot hang I'm seeing on ThunderX1.

The register offsets are different between Octeon and ThunderX so move
them into the algorithm struct and get rid of the define.

This is an intermediate commit in preparation of the driver split.
The module rename in this commit will be reverted in the next patch,
this is just done to make the series bisectible.

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.

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

Add ThunderX SPI driver using the shared part from the Octeon
driver. The main difference of the ThunderX driver is that it
is a PCI device so probing is different. The system clock settings
can be specified in device tree.

Switched to new cpuhp stuff. I still don't care about the CPU location
used to access an uncore device, it may cross the CCPI and
we'll pay a performance penalty. We might optimize this later, for now
I feel it is not worth the time optimizing it.
