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