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.

This change adds a helper function `fw_config_probe_dev()` that allows
the caller to check if any of the probe conditions are true for any
given device. If device has no probe conditions or a matching probe
condition, then it returns true and provides the matching probe
condition back to caller (if provided with a valid pointer). Else, it
returns false. When fw_config support is disabled, this function
always returns true.

`probe_list` member in `struct device` is present in all stages,
however, util/sconfig emits the list only when !DEVTREE_EARLY. This
change ensures that `probe_list` is emitted in all stages. In follow
up changes, this is used to get the correct device state using probe
conditions.

fw_config is unprovisioned in the factory for the first boot. This is
the only case where fw_config is left unprovisioned. On first boot in
factory, fw_config gets correctly provisioned by the factory
toolkit. When fw_config is unprovisioned, it is not always possible to
make a guess which device to enable/disable since there can be certain
conflicting devices which can never be enabled at the same time. That
is the reason the original implementation of fw_config library kept
fw_config as 0 when it was unprovisioned.
CB:47956 ("fw_config: Use UNDEFINED_FW_CONFIG to mean unprovisioned")
added support for a special unprovisioned value to allow any callers
to identify this factory boot condition and take any appropriate
action required for this boot (Ideally, this would just involve
configuring any boot devices essential to getting to OS. All other
non-essential devices can be kept disabled until fw_config is properly
provisioned). However, CB:47956 missed handling the
`fw_config_probe()` function and resulted in silent change in behavior.
This change fixes the regression introduced by CB:47956 and returns
`false` in `fw_config_probe()` if fw_config is not provisioned yet.

commit ce0e2a0140 (drivers/intel/fsp2_0:
use FSP to allocate APEI BERT memory region) adds a mechanism to reserve
the BERT region inside the coreboot code, so we can get rid of the
workaround to reserve it in the FSP and return the location in a HOB.
mcfg->bert_size defaults to 0 which makes the FSP not generate the
corresponding HOB, but that field is planned to be removed at least on
Cezanne, so don't explicitly set it to 0.

Most of the time when INIT_BOOTBLOCK is selected, the cache should be
empty here anyway, so this is a no-op. But when it's not empty that
means the bootblock loaded some other file before it got to the TPM
init part (which is possible, for example, if hooks like
bootblock_soc_init() load something).
