Subject: [PATCH V1] i2c: tegra: fix tegra186 hw supported features
Tegra186 does not support multi-master mode and also there is no
master fifo control register.
This patch fixes supported features of Tegra186 and prevents
crashing during boot as master fifo control register are not
present on Tegra186 and prior.
