mb/system76/oryp5: Configure dGPU GPIOs in bootblock
Configure the dGPU power and reset pins in bootblock instead of
ramstage. This fixes a conflict with our downstream driver, which
configures these pins to enable dGPU power in romstage. Behavior remains
unchanged without the driver as the dGPU is left powered off.
