b1e4a9a6c3 mb/siemens/mc_ehl: Move UART_FOR_CONSOLE switch to variant level
There are currently two variants for mc_ehl where different UARTs are
used for the console. Move the Kconfig switch UART_FOR_CONSOLE to the
Kconfig of the variant and select the matching value there.

264ace99e8 mb/siemens/mc_ehl: Add a new variant mc_ehl2
Add a new variant of the mc_ehl board called mc_ehl2. This patch just
copies the files and renames things where needed.
Following patches will adapt the needed features for this new variant.

0dcdb217cf soc/intel/common: Use CHIPSET_LOCKDOWN_COREBOOT by default
Since all mainboards use `CHIPSET_LOCKDOWN_COREBOOT`, make it the
default by changing its enum value to 0 and remove its configuration
from all related devicetrees.

If `common_soc_config.chipset_lockdown` is not configured with
something else in the devicetree, then `CHIPSET_LOCKDOWN_COREBOOT`
is used.

Also, add a release note for the upcoming 4.15 release.

78ec750610 mb/siemens/mc_ehl: Enable master bit in PCI config space if allowed
Some legacy devices need to have the master bit set in the PCI config
due to old drivers not setting it correctly. Set the master bit if the
feature is enabled via Kconfig switch PCI_ALLOW_BUS_MASTER_ANY_DEVICE.

For now, the PCI devices with the ID 110a:403e and 110a:403f needs this
master bit to be set.

4cec1a2770 mb/siemens/mc_ehl: Add code to wait for legacy devices before PCI scan
Boards based on mc_ehl have, just like some mc_apl variants, legacy
devices on the PCI bus which take longer to boot. In order to ensure
that they will be enumerated correctly wait for them to come up before
PCI scan starts.

TEST=Checked that the new message is visible in the log.

cf35fd3748 mb/siemens/mc_ehl1: Disable L1 substates for PCIe root ports
L1 substates of a PCIe link are meant to save some power when the link
is not active but have the drawback that the PCIe latency is increased
as PLLs are switched on and off as needed.

In order to get a better realtime performance, disable all substates for
every PCIe root port.
