platform/x86: x86-android-tablets: Fix Lenovo Yoga Tablet 2 830F/L vs 1050F/L detection

gpio_crystalcove pin 10 is already in input mode and passing GPIOD_IN
when requesting the GPIO changes its pull-up/-down settings causing
the 830F/L to get misdetected as 1050F/L.

Switch to using GPIOD_ASIS when requesting the GPIO to fix
the misdetection.
