Ignore I2C_M_DMA_SAFE flag as it does not make a difference
for bpmp-i2c, but causes -EINVAL to be returned for valid
transactions.

I wonder if bailing out on an unknown flag shouldn't be revisited in
general? I mean this will happen again when a new I2C_M_* flag is
introduced.


If it's guaranteed that any new flags are optional to handle by the driver, than that is certainly better. I'll post a v3 with that approach.

thanks,
Mikko
