Subject: [PATCH 2/2] ARM: DRA7: hwmod_data: Change locked_class for atl hwmod

The ATL hwmod can be used in nested way when it is selected to be the
functional clock for McASP. For this lockdep validator will trigger false
positive warning.
By assigning separate class to atl locking will sort this out.
