[PATCH] hwmon: Add a new macro sensor_sysfs_attr

[Ma Jun <Jun.Ma2@amd.com>]

The attribute definiations like &sensor_dev_attr_xx_xx.dev_attr.attr
are widely used in drivers. So add a new macro sensor_sysfs_attr t
to make it easier to understand and use.

For example, user can use the sensor_sysfs_attr(xx_xx) instead of
&sensor_dev_attr_xx_xx.dev_attr.attr
