Alexander Kochetkov 940f3bbf3d spi: rockchip: enable autosuspend feature ...

If SPI is used for periodic polling any sensor, significant delays
sometimes appear. Switching on module clocks during resume lead to delays.
Enabling autosuspend mode causes the controller to not suspend between
SPI transfers and the delays disappear.
