cr50: add support for creating multiple serial endpoints

Browse Source 
CR50 will need three serial endpoints for the streaming AP and EC UART
and exporting its own console through USB. This change adds a macro to
create endpoints that can be recognized by the usb_serial driver.

BUG=chrome-os-partner:50702
BRANCH=none
TEST=Verify "/dev/google/Cr50*/serial/Blob" prints capital letters when
lower case letters are input.
