cr50: add command for forcing servo disconnect
Early proto boards may not have the servo detection setup correctly.
This change adds a method to work around this issue, so people can use
the consoles even if cr50 thinks servo is connected.
BUG=b:119690767
BRANCH=cr50
TEST=Use 'ccdblock ignore_servo enable' on cheza EVT verify ec uart
becomes read write. Make sure uart becomes read only after 'ccdblock
ignore_servo disable'.
