mb/google/dedede: Configure VCCIOSEL for EN_SPKR GPIO Pad
Realtek speaker amplifiers under auto mode operation have Absolute Max
Rating (AMR) at 1.98 V. Hence probe the firmware config for speaker
amplifier and program the VCCIOSEL accordingly.
BUG=b:194120188
TEST=Build and boot to OS in Storo. Ensure that the VCCIO selection is
configured as expected and probing the GPIO reads the configured
voltage.
