tegra-helper-scripts: use 'sparse update' of SPI flash by default

Browse Source 
The tegraflash.py script takes a '--sparseupdate' option that causes
it to update only changed partitions in the SPI flash. Enable that
by default in the flash helper script, and add an --erase-spi option
to force full erasure of the SPI flash, in case that's needed.
