arm64: tegra: Remove the Orin NX/Nano suspend key

Browse Source 
[ Upstream commit bb8a3ad25f098b6ea9b1d0f522427b4ad53a7bba ]

As per the Orin Nano Dev Kit schematic, GPIO_G.02 is not available
on this device family. It should not be used at all on Orin NX/Nano.
Having this unused pin mapped as the suspend key can lead to
unpredictable behavior for low power modes.

Orin NX/Nano uses GPIO_EE.04 as both a "power" button and a "suspend"
button. However, we cannot have two gpio-keys mapped to the same
GPIO. Therefore remove the "suspend" key.
