arm: omap2plus: fix ads7846 pendown gpio request
introduced by: 96974a24 (omap: consolidate touch screen initialization among different boards) ads7846 driver can use either gpio_pendown or get_pendown_state() callback. In case of gpio_pendown, it requests the provided gpio_pendown thus resulting in double requesting that gpio: ads7846 spi1.0: failed to request pendown GPIO57 ads7846: probe of spi1.0 failed with error -16 Fix this by restricting the gpio request to the case of get_pendown_state() callback is used.
