mb/google/zoombini: always report EC is in RO mode 

Always report that EC is in RO mode.  This is a temporary workaround
for a hardware issue that is causing EC to appear to be in RW mode
when it is not.  This change will be reverted once transition is made
to newer hardware.

BUG=b:74215817
BRANCH=master
TEST=Verify meowth can boot to recovery's insert screen.
