commit 84807922874e03895bbf15c4472a2dcee8fbbd03
("spi: omap3: Skip set_mode, set_speed from claim") did break SPI
support on my AM335x board.The named commit: - ignored the responsible arguments (speed, mode) The set speed/mode function must use the supplied function arguments to work properly. With this commit we take those arguments and transfer them to the priv-data. - used wrong udevice pointer for getting priv data the udevice-pointer within function argument is already the spi-bus device, so it is wrong looking here for some parent (ocp-bus in this case) and getting priv-pointer from there.
