Randall Spangler 267dbb74d2 Add common interface to EC flash commands
ectool and burn_my_ec need to use the same lower-level interface to
the EC flash commands, rather than duplicating calling the low-level
flash read/write/erase commands.

This is a precursor to refactoring the low-level commands to support
SPI/STM32L in a follow-up CL.

BUG=chrome-os-partner:20571
BRANCH=none
TEST=in a root shell, burn_my_ec flashes both RO and RW EC code
