google/cyan: convert to variant configuration 

Setup cyan to be the baseboard for other Google Braswell
boards, to be added in subsequent commits:

- Keep code common to all Google Braswell boards in the baseboard,
and separate out the board-specific bits into the new cyan variant.

- Define the I2C ACPI devices such that they can be easily reused for
other variants.

- Switch the trackpad/touchscreen interrupts from edge to level,
for better performance/compatibility, as was done with all previous
Google boards.

- Add code to the baseboard to allow optional variant-specific
parameters to be used for both memory and silicon init.

- Remove superfluous includes, replace some hardcoded values with
variables, and correct typos/formatting errors.
