i2c: bpmp-tegra: Ignore unknown I2C_M flags
In order to not to start returning errors when new I2C_M flags are added, change behavior to just ignore all flags that we don't know about. This includes the I2C_M_DMA_SAFE flag that already exists but causes -EINVAL to be returned for valid transactions.
