spi/tegra114: Factor runtime PM out into transfer prepare/unprepare
Currently the tegra114 driver acquires a runtime PM reference for the
duration of each transfer. This may result in the IP being powered down
between transfers which would be at best wasteful. Instead it is better
to do this in the callbacks that are generated before and after starting
a series of transfers, keeping the IP powered throughout.
