TEMP: remove verification from bossacI tool

This completely removes the verification phase, speeding up the compile/upload/test cycle.
The patch can be reverted if:
* we release a new version of bootloader + VidorBoot combo where checksum is internally calculated by the FPGA
* we patch bossac to avoid asking the checksum for locations over internal flash size
