by the ipmi-ssif driver.

Add support for reading the system clock and the TWSI clock
frequency from ACPI DSDT.
TWSI clock was already covered by using device_property_read().

Using pci_alloc_irq_vectors() instead of the deprecated
pci_enable_msix() allows to remove the msix_entry from
struct octeon_i2c and thus to get rid of the config symbol check.

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

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

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.
