The Moonstone hardware design does not have a power load switch for
the SSD. Without it, the platform cannot cut off the main power rail
to the device to enter D3cold.
Therefore, remove the RTD3 chip driver and its associated GPIO
configurations (enable/reset) in the overridetree to align with the
hardware capability. The system will support D3hot instead of D3cold.
BUG=460038237
TEST=Build and boot to OS on Moonstone, verify SSD still functions
correctly and power state transitions align with HW design.
