Xiang Chen 1e82e4627a scsi: libsas: Resume SAS host for phy reset or enable via sysfs
Currently if a phy reset or enable phy is issued via sysfs when controller
is suspended, those operations will be ignored as SAS_HA_REGISTERED is
cleared. If RPM is enabled then we may aggressively suspend automatically.
In this case it may be difficult to enable or reset a phy via sysfs, so
resume the host in these scenarios.
