CBI: Allow get command to reload data from EEPROM
This patch adds CBI_GET_RELOAD flag to EC_CMD_GET_CROS_BOARD_INFO
command. When the flag is set, the command will be forced to read
data from EEPROM even, ignoring the data cached by the previous
read.
This allows ectool to verify a write was successful without reboot.
BUG=b:70294260
BRANCH=none
TEST=ectool cbi set 0 0x1234 && ectool cbi get 0 1
