Nicolas Boichat 39db721f9a hammer: Add board_get_entropy function (and test) 
This function will be used to generate some entropy using the
Clock Recovery System.

BRANCH=none
BUG=b:38486828
TEST=make BOARD=hammer -j tests
     ./util/flash_ec --board=hammer --image=build/hammer/test-entropy.bin
     EC console: runtest
TEST=Test fails when no USB connection is active
TEST=Test passes when USB connection is active
TEST=Pasting the values into:
     tr ';' '\n' | awk 'BEGIN { e = 0; tot=16384.0 }
                  { p = $1/tot; if (p > 0) { e -= p*log(p)/log(2) } }
                  END { print e }'
     shows an entropy > 4 bits per sample.
