jostar-yang 5c83be5d28 Add support for Accton AS7712-32X platform (#1299)
* Add support as7716_32x sfp/psu/portled/eeprom

* Add as7716_32x drv code(not inlcude .*.o)

* Update platform-modules-accton.mk

* Update platform-modules-accton.mk

1.Modify platform-modules-accton.mk to use new style code add_extra_package
2. fix error code

* Add as7716_32x build to debian control,rule

* Add as7716_32x export
