FCH_AOAC_UART_FOR_CONSOLE will only be used in the code if
PICASSO_CONSOLE_UART is selected, so only check if it's a valid value in
this case.

The code on Stoneyridge didn't set the FCH_AOAC_TARGET_DEVICE_STATE bits
to FCH_AOAC_D0_INITIALIZED like the code for Picasso does, but that is
the default value after reset for those bits on both platforms.

The register locations and bit definitions are the same for Stoneyridge
and Picasso. Since not all devices are present on all SoCs, keep those
numbers in the SoC-specific code.

The power_off_aoac_device function clears the FCH_AOAC_PWR_ON_DEV bit,
so the comment should be that it powers off the devices.
