There are 2 issues here: 1. top_en register is being masked for each leaf level interrupt disable operation. top_en bit should be disabled as part of top level stall operation only. 2. Wrong mask is being calculated to disable the leaf_en bits for a unit which inturn affects the entire subtree. Subtree_mask_restore for a subtree stores the last state of interrupts that are enabled. As part of disable operation, we only need to update subtree_mask_restore and not reupdate subtree_mask for that subtree. Same logic applies to enable operation. Renamed the apis to better reflect their operation. The interrupt disabling is done at unit level and not subtree level.
