spi: mt65xx: add PM QoS support

Enable Quality of Service(QoS) support to speed up interrupt service
routine handle. Sometimes, a gic interrupt will be generated after
SPI transmission, but at this time the CPU is in an idle state and the
processing handler will be very slow. It takes time to exit the idle state
and then become active. This will cause the SPI handler to execute slowly
and cause SPI transfer timeouts.
