Linux kernel expects that power management with ACPI should always be
handled using PowerResource. However, some kernel drivers (e.g. ELAN
touchscreen) check to see if reset gpio is passed in by the BIOS to
decide whether the device loses power in suspend. Thus, until the kernel
has a better way for drivers to query if device lost power in suspend,
we need to allow passing in of GPIOs via _CRS as well as exporting
PowerResource to control power to the device.
Update mainboards to export reset GPIO as well as PowerResource for
ELAN touchscreen device.
BUG=chrome-os-partner:62311,chrome-os-partner:60194
BRANCH=reef
TEST=Verified that touchscreen works on power-on as well as after
suspend-resume.

This commit makes the initial changes to support the Intel Leaf Hill
CRB with Apollo Lake silicon. Memory parameters and some GPIOs are set.
The google/reef directory is used as a template, and the same IFWI
stitching process as reef is used to generate a bootable image.
Apollo Lake silicon requires a boot media region called IFWI which includes
assets such as CSE firmware, PMC microcode, CPU microcode, and boot
firmware.

This commit adds the initial scaffolding for the Intel Leafhill CRB
with Apollo Lake silicon.
The google/reef directory is used as a template. This commit only
makes the minimum changes to Kconfig and Kconfig.name needed for
the build bot to not have issues.
