Qiu Peiyang b549e0fbca spi_qmsi_ss: add device_busy_set() to avoid re-enter deep sleep 
When CONFIG_SYS_POWER_DEEP_SLEEP is enabled, spi_qmsi_ss will
keep entering deep sleep because it needs to wait until the
current transfer completes, which blocks the current thread.
The system keeps entering deep sleep again and again and the
transfer will never complete.

Add device_busy_set() to spi_qmsi_ss driver to indicate that
the device is busy and block the system from entering deep
sleep during transaction.
