In Nomadik I2c controller, register I2C_MCR has 11-bit wide LENGTH
field. Its maximum value is 2047, so this is the maximum length of a
single message. It is less than the common maximum I2C message length in
I2C subsystem (8192), so define a quirk in order to report the
unsupported message without any attempt to transfer it.

Zero length reading doesn't work properly on this controller, so add
`I2C_AQ_NO_ZERO_LEN_READ` quirk flag.
