mpc52xx_spi: add gpio chipselect
This one enables the mpc52xx_spi driver for usage of user defined gpio lines as chipselect. This way we can control some more spi devices than only one V2 Changes: * preinitialize the gpio as output in probe function and call gpio_set_value in the chip select function instead of calling direction_output every time. * initialize the gpio line with output high, since we don't support CS_HIGH in the driver currently any way. change gpio value setting to default active low in chip select call. * free the gpio array while error or removing.
