[ARM] tegra: nvrm: remove GART allocation from I2C driver
The problem is that some drivers can keep GART memory pinned, fragmenting
it and making impossible to pin the memory allocated in other process.
24M limit on GART made situation less probable but didn't solve it
completely.
This fix disables GART allocation for ap20rm_i2c driver.
