i2c: imx: add I2C_M_REV_DIR_ADDR and I2C_M_NOSTART
The Realtek RTL8366SE SMI read frame per:
S Addr Rd [A] reg[7:0] [A] reg[15:8] [A] [data[7:0]] A [data[15:8]] NA P
Linux support it using I2C_M_REV_DIR_ADDR on a write message
that inverts the transmitted R/W bit, and I2C_M_NOSTART on the following
read message that continues the frame without re-addressing.
This NXP i2c-imx is missing such support, so on an LX2160A the Realtek switch
could not be used.
