zdev: add functionality to read site-specific settings

Browse Source 
Modify the dev_get_setting_list function to get the site-specific
attributes of the device. The new site_id parameter for this function
must be less than SITE_FALLBACK to read the site-specific attributes.
As SITE_FALLBACK setting is same as persistent setting, we do not need
a separate read function for it.
