measurement is supported for now.
Changes from v9:
1. minor changes.
2. pass microamps from dts, not register value.
Changes from v8:
1. add vcnl3020 prefix into get_and_apply_property function.
2. add bsd license into yaml.
3. vishay,led-current-milliamp -> vishay,led-current-microamp.
4. add default value into vishay,led-current-microamp and change
register values into microamps.
Changes from v7:
1. forgot to add Reviewed-by tag.
Changes from v6:
1. minor changes
1.1 remove VCNL_DRV_NAME
1.2 add braces in get_and_apply_property

2. led-current -> vishay,led-current-milliamp in yaml.
3. add possible values enum list.
4. add bulk_read for result hi/lo registers.
5. add description of vcnl3020_data structure.
6. vcnl3020 id table is removed.
7. make "vishay,led-current-milliamp" optional in yaml and code.
Changes from v3:
1. minor changes.
2. add i2c block to fix dts section in yaml.
Changes from v2:
1. using regmap_read_poll_timeout instead of do-while in measurement
function.
2. change struct i2client* in vcnl3020_data to struct dev*
3. enable REGMAP_I2C in Kconfig
