5d6a0d0ec7 sw: webusb: fix landing descriptor warning 
For some reason, -flto didn't like the "extern const struct" definition.
Hide the variable now and use an accessor function to silence this
warning, which may have caused other issues with stability.

646388fcb7 sw: dfu: fix calculation for address offset 
We were using the wrong offset for address calculation.  Use the block
size, rather than the program size.  This wasn't an issue before, because
the block size and the program size were both 256 bytes.  Now the block
size can be 1024 bytes.
