i2c: tegra: remove support for I2C_M_REV_DIR_ADDR
The Tegra i2c controller actually can not support the reverse of
direction address (toggling r/w bit of address) as controller
take 7 bit address from configuration and HW make it 8 bit address
based on read/write flag.
Hence reverting this protocol mangling support.
