hwmon: (pmbus/ibm-cffps) max_power_out swap changes
[ Upstream commit f067d5585cda2de1e47dde914a8a4f151659e0ad ]
The bytes for max_power_out from the ibm-cffps devices differ in byte
order for some power supplies.
The Witherspoon power supply returns the bytes in MSB/LSB order.
The Rainier power supply returns the bytes in LSB/MSB order.
The Witherspoon power supply uses version cffps1. The Rainier power
supply should use version cffps2. If version is cffps1, swap the bytes
before output to max_power_out.
Tested:
Witherspoon before: 3148. Witherspoon after: 3148.
Rainier before: 53255. Rainier after: 2000.
