Peng Fan 52dd070c62 pmdomain: imx: wait SSAR when i.MX93 power domain on
With "quiet" set in bootargs, there is power domain failure:
"imx93_power_domain 44462400.power-domain: pd_off timeout: name:
 44462400.power-domain, stat: 4"

The current power on opertation takes ISO state as power on finished
flag, but it is wrong. Before powering on operation really finishes,
powering off comes and powering off will never finish because the last
powering on still not finishes, so the following powering off actually
not trigger hardware state machine to run. SSAR is the last step when
powering on a domain, so need to wait SSAR done when powering on.

Since EdgeLock Enclave(ELE) handshake is involved in the flow, enlarge
the waiting time to 10ms for both on and off to avoid timeout.
