Disable master interrupt before reading level indications. This will close a race where we get a level indication between reading and disabling, generating an extra interrupt where we could have avoided one. Further, as the reading acts also as a post, replace the write/post on the irq reset with the helper. On enabling side, posting doesn't serve any purpose so it can also be replaced with helper.
