Add additional chip ID for an older revision of LTC2978, as well as two chip IDs for LTC3882. Turns out the LTC3882 does support the LTC2978_MFR_SPECIAL_ID register, and reading it returns its chip ID, but the register is undocumented.

Per datasheet, the chip ID for LTM4676 is 0x448x. This was observed in real systems. In addition to that, chip ID 0x4401 was observed as well. Research shows that the chip ID has been changed from 0x440x to 0x448x in datasheet revision C. Add support for the additional chip ID. Also add the chip ID for LTM4676A, which is functionally identical to LTM4676.

MAX20751 is a multiphase power controller with internal buck converter. It uses VR12.0 to report the output voltage. This requires an explicit driver, since the VR version can not be auto-detected. The chip supports a manufacturer specific command to fine-tune the output voltage. This command is not currently supported. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

The temperature value of Fintek F81866 is the same with f71882fg. It located with 0x6c + 2*(nr), others located with 0x6c + 2*(nr+1). We change the rule in f71882fg_probe(), If type = f71858fg/f8000/f81866a. the temp_start will set to 0, others are 1. The F81866 over-temperature beep setting is not the same with f71882fg too. They are using the same address 63H, but F81866 is using bit 0/1/2 & 4/5/6, others are using bit 1/2/3 & 5/6/7, So we copy from fxxxx_temp_beep_attr[] to f81866_temp_beep_attr and change bit setting.
