libata: port and host should be stopped before hardware resources are released
Port / host stop calls used to be made from ata_host_release() which
is called after all hardware resources acquired after host allocation
are released. This is wrong as port and host stop routines often
access the hardware.
Add separate devres for port / host stop which is invoked right after
IRQ is released but with all other hardware resources intact. The
devres is added iff ->host_stop and/or ->port_stop exist.
This problem has been spotted by Mark Lord.
