The Tegra SPI driver supports runtime PM, which controls the clock enable state, but the clk is also enabled separately from the RPM at the driver probe time, and thus, stays always on. Fix it.
Runtime PM now is always available on Tegra, hence there is no need to check the RPM presence in the driver anymore. Remove these checks.
This feels new featureish to me - it'll give you runtime PM where previously there was none.
