Modify the spi flash driver to allow smaller read IO sizes, but enforce
...
the larger, aligned write+erase sizes the driver currently implements.
This preserves write behaviour but makes the flash driver usable for things
like a read-only FFS or a geom_uzip/geom_compress .
Note that since GEOM will now return the sector size as being smaller,
writes of sector size/alignment will now fail with an EIO. Code which
writes to the flash device will have to be (for now) manually taught
about the flash write blocksize.

Add support for the m25p64; lifted straight from Linux.
...
This flash chip is found on the Ubiquiti LS-SR71 board.
I've successfully tested reading; I've not tried writing to it yet.

Extend the mx25l flash device support to include a set of per-device
...
flags.
Some of these parts will support 4K/32K block erases rather than
a sector erase. This includes (at least) the MX25L128.
