Update libata SATA LLDs to use devres. Core layer is already
converted to support managed LLDs. This patch simplifies
initialization and fixes many resource related bugs in init failure
and detach path. For example, all converted drivers now handle
ata_device_add() failure gracefully without excessive resource
rollback code.
As most resources are released automatically on driver detach, many
drivers don't need or can do with much simpler ->{port|host}_stop().
In general, stop callbacks are need iff port or host needs to be given
commands to shut it down. Note that freezing is enough in many cases
and ports are automatically frozen before being detached.
