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.
