Subject: [PATCH v2 0/3] pmbus: ibm-cffps: Add support for version 2 of PSU

Version 2 of this PSU supports a second page of data and changes the
format of the FW version command. Use the devicetree binding (or the I2C
device ID) to determine which version the driver should use. Therefore add
the new compatible string to the devicetree documentation and change the
Swift system devicetree to use version 2.

Changes since v1:
 - use an enum for the version instead of integers 1, 2, etc
