i2c: cros_ec: Remove EC_I2C_FLAG_10BIT
In <https://lkml.org/lkml/2014/6/10/265> pointed out that the 10-bit
flag in the cros_ec_tunnel was useless. It went into a 16-bit flags
field but was defined at (1 << 16).
Since we have no 10-bit i2c devices on the other side of the tunnel on
any known devices this was never a problem. Until we do it makes
sense to remove this code. On the EC side the code to handle this
flag was removed in <https://chromium-review.googlesource.com/204162>.
