rex: Fix the gpio pin type for ec_edp_bl_en
The gpio device tree node for ec_edp_bl_en was being configured as an
open-drain signal, but this should be a TTL with low as its initial
state. This CL corrects this error. The GPIO spreadsheet that's being
used as an input for pinmap needs to be updated. This CL provides a
fix to enable the display panel to work until the tool that creates
the input for pinmap is updated.
