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.
