spi: omap3: fix set_speed and set_mode dm callbacks

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.
