fwflash for sd needs to handle partial writes
For more background on this problem, please see https://github.com/joyent/rfd/blob/master/rfd/0031/README.md. The high level problem is that we have firmware images whose size is larger than the amount of memory we can write in a single DMA buffer.
To handle this, we've added the ability to get the maximum size we can write from a device. We then say that if the firmware image is larger than the device size, we instead will do series of partial writes to the controller to perform the firmware upgrade. However, if it fits, then we'll instead opt to do the single traditional write.
