This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

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.

I2C data (GPIO_132) and Clk (GPIO_133) lines are pulled low during
standby states S3/S0ix. This causes leakage of power. To reduce the
leakage, we have to pull these lines high during S3/S0ix. This is
done by programming the IOSSTATE to HIz. Also note that we are using
the internal pull ups to keep at SOC at 1.8V and the I2C lines are
not floating.

TEST=Enter S3/S0ix. Measure trackpad power. It should be less
than 4mW. Also I2c lines should be pulled high in S3/S0ix.

Wacom touchscreen is i2c hid device and it's the device that always
exists.
So no need to set "probed" property for it.
