mach-qt2410: convert to spi_gpio
Rather than the deprecated spi_s3c24xx_gpio driver. Only compile tested. Notice that the board support seems quite broken as the spi_s3c24xx_gpio platform device name was misspelled and there is no struct spi_board_info defined, but this atleast didn't make it any worse.
