ec/google/wilco: Add a bootblock function for early init
Add a function for use in bootblock stage that performs early init
of the EC, in particular setting it up for UART passthrough so a
legacy serial port can be used by the host.
This needs to be called by the mainboard that intends to use it
in bootblock in order for the UART to be available in later stages.
Some of the PNP style programming may look odd, but it is following
the EC specification which is not entirely standard. This code has
been tested on a board with this EC and it is functional.
