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.

Already released Linux versions did not have the needed ACPI-extension
in the RTC driver. If the ACPI-Support is enabled for the RTC, this
older Linux will not be able to use this device as it will be claimed by
the PNP-drivers. As there is no way to avoid that an older Linux kernel
meets a newer coreboot in the field, we need to disable the ACPI
support for the RTC for the mc_apl-based mainboards.

Variant mc_apl1 is the only one that uses gpio.c from baseboard. For
this reason, gpio.c is moved from baseboard to mc_apl1.

With commit 405f229689 (soc/intel/*: drop UART pad configuration from
common code) the UART pad configuration was dropped from common SoC
code. Through a second commit 5ff17ed393 (mb/siemens/mc_apl1: do UART
pad configuration at board-level) the UART pad configuration was made
for mc_apl1 baseboard. This change is also needed for all other mc_apl
boards.

The CMOS option system does not support negative integers. Thus, retype
and rename the option API functions to reflect this.

All the boards in the patch have a constraint for the I2C bus to operate
on 100 kHz. Provide dedicated values for rise time, fall time and data
hold time on mainboard level to get a proper timing which takes the bus
load into account. Giving these values the driver computes the needed
timings correctly.
TEST=Measure I2C frequency on all boards while coreboot accesses
external RTC and make sure it is 100 kHz.

All related mainboards are setting DIMM_SPD_SIZE to 512. Therefore,
default to 512 in the SoC Kconfig and drop it from related mainboard
Kconfigs.
