Todd Broch b9b457173e pd: hoho: mcdp28x0 serial driver.

Add initial serial driver for mdcp2850 dp->hdmi converter.  Driver
implements 'get information' (cmd:0x40) to provide rudimentary method
to test mcdp for functionality and assert GPIO if successful.

Future CLs may expose more serial functionality if necessary.

BRANCH=samus
BUG=chrome-os-partner:34122
TEST=manual, when compiles with #define MCDP_DEBUG see successful
serial communication and result from get info.
