west.yml: hal_atmel: Add include directory only for atmel devices

The main CMakeLists.txt for hal_atmel adds an include directory
without checking that the module is enabled. This causes ALL Zephyr
builds to have modules/hal/atmel/include in their included
directories. This commit updates west.yml to point to a fix for
this issue.
