[ Upstream commit e4bb903fda0e9bbafa1338dcd2ee5e4d3ccc50da ]

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.

Apparently all patches which have a word 'fix' in commit message are
auto-selected. I agree that it's better not to port this patch.
