device: Consider fw_config probing in `is_dev_enabled()`
With the introduction of fw_config support in coreboot, it is possible
for mainboards to control the state of a device (on/off) in ramstage
using fw_config probe conditions. However, the device tree in
immutable in all other stages and hence `is_dev_enabled()` does not
really reflect the true state as in ramstage.
This change adds a call to `fw_config_probe_dev()` in
`is_dev_enabled()` when device tree is immutable (by checking
DEVTREE_EARLY) to first check if device is disabled because of device
probe conditions. If so, then it reports device as being
disabled. Else, dev->enabled is used to report the device state.
This allows early stages (bootblock, romstage) to use
`is_dev_enabled()` to get the true state of the device by taking probe
conditions into account and eliminates the need for each caller to
perform their own separate probing.
