Patrick Rudolph a607d831c0 drivers/i2c/at24rf08c: Add option for early locking 
Currently the Sandybridge Lenovo devices are spending 25msec waiting
for ME to signal if RAM has been replaced. At the same time the RFID
I2C EEPROM needs to be locked, taking about 26msec.

By moving the locking to romstage the time spent waiting for ME can
be used to do something useful and thus reduce boot time.

TEST=On Lenovo X220 it boots 24msec faster.
