[PATCH v2] ARM: eukrea_mbimx27-baseboard - use stockget_pendown_state() in ads7846

[Dmitry Torokhov]

The default implementation matches exactly our custom one so we can switch
to using the default one. As a bonus the driver will take care of setting
GPIO line for us.

Adjusted to use IMX_GPIO_NR() macro.
