hwmon: (pmbus/mp2975) Correct comment inside 'mp2975_read_byte_data'

Browse Source 
The current driver code no longer perfrom internal conversion from
VID to direct. Instead it configures READ_VOUT using MFR_DC_LOOP_CTRL.
Correct the comment message inside the 'mp2975_read_byte_data'
function to match the driver logic.
