43f33b6e59 hwmon: (pmbus) Add 'phase' parameter where needed for multi-phase support
In preparation for multi-phase support, add 'phase' parameter to read_word
and set_page functions. Actual multi-phase support will be added in
a subsequent patch.

deddc9e8c0 hwmon: (pmbus/xdpe12284) Add callback for vout limits conversion
Provide read_word_data() callback for overvoltage and undervoltage
output readouts conversion. These registers are presented in
'slinear11' format, while default conversion for 'vout' class for the
devices is 'vid'. It is resulted in wrong conversion in pmbus_reg2data()
for in{3-4}_lcrit and in{3-4}_crit attributes.
