Apollo Lake SoC supports configuration of Running Average Power Limits
(RAPL) for package domain. This feature is not required for all APL
mainboards. According to the APL SoC EDS Vol 4 chapter 18.4 Power
Limiting Control it is not necessary to enable the RAPL algorithm per
default. For that reason make the RAPL configuration selectable.

Sadly, small core and big core are not aligned with the OS driver's
expectation on the number of ACPI devices used for each community.
Big core uses a single device while small cores use one ACPI device
per community. Allow for this distinction within the common gpio
implementation and ensure apollolake is utilizing the new option
to retain the correct behavior.

Update default ODT config to have correct CA ODT settings as the
current defaults are incorrect for all the current apollolake designs.
All the current designs pull both A and B channels' LPDDR4 modules' ODT
pins to 1.1V. Therefore, the correct impedance setting needs to be
applied.
In order for the settings to take effect one needs to clear the
memory training cache in deployed systems. Trigger this by bumping
the memory setting version for the SoC.
If needed in the future support for allowing the override of this
setting from the mainboard should be straight forward. It's just not
necessary at this time.

The virtualized developer switch was invented five years ago and has
been used on every vboot system ever since. We shouldn't need to specify
it again and again for every new board. This patch flips the Kconfig
logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with
CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to
set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the
latter for Lumpy which seems to have been omitted incorrectly, and hide
it from menuconfig since it's a hardware parameter that shouldn't be
configurable.)
Since almost all our developer switches are virtual, it doesn't make
sense for every board to pass a non-existent or non-functional developer
mode switch in the coreboot tables, so let's get rid of that. It's also
dangerously confusing for many boards to define a get_developer_mode()
function that reads an actual pin (often from a debug header) which will
not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set.
Therefore, this patch removes all those non-functional instances of that
function. In the future, either the board has a physical dev switch and
must define it, or it doesn't and must not.
In a similar sense (and since I'm touching so many board configs
anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC.
Instead, it should just be assumed by default whenever a Chrome EC is
present in the system. This way, it can also still be overridden by
menuconfig.
