Subject: [PATCH v3 0/2] hwmon: (adm1275) Add sample averaging binding support

This patch series allow user config PWR_AVG and VI_AVG in PMON_CONF
register by adding properties in device tree.

Example:
	adm1278@11 {
		compatible = "adi,adm1278";
		......
		adi,volt-curr-sample-average = <128>;
		adi,power-sample-average = <128>;
	};

LINK: [v1] https://lore.kernel.org/all/20220223163817.30583-1-potin.lai@quantatw.com/
LINK: [v2] https://lore.kernel.org/all/20220224154329.9755-1-potin.lai@quantatw.com/

Changes v2 --> v3:
- change property type back to u32, use logical value instead of register
  value
- fix typo in properties description
- add if-block to descript "adi,power-sample-average" not alloed if
  compatible not in the enum list

Changes v1 --> v2:
- use more descriptive property name
- change property type from u32 to u8 
- add property value check, valid range between 1 and 7
