Subject: [PATCH 09/14] arm64: dts: qcom: sc7180: Remove superfluous "input-enable"s from trogdor

As talked about in the patch ("dt-bindings: pinctrl: qcom: tlmm should
use output-disable, not input-enable"), using "input-enable" in
pinctrl states for Qualcomm TLMM pinctrl devices was either
superfluous or there to disable a pin's output.

Looking at trogdor:
* ap_ec_int_l, fp_to_ap_irq_l, h1_ap_int_odl, p_sensor_int_l:
  Superfluous. The pins will be configured as inputs automatically by
  the Linux GPIO subsystem (presumably the reference for other OSes
  using these device trees).
* bios_flash_wp_l: Superfluous. This pin is exposed to userspace
  through the kernel's GPIO API and will be configured automatically.

That means that in none of the cases for trogdor did we need to change
"input-enable" to "output-disable" and we can just remove these
superfluous properties.
