Summary

Some hardware/firmware leaves serial console in bogus state before calling user boot code. After that output of boot0sio could not be seen by user, which is inconvenient.
This diff adds compile-time option BOOT_BOOT0_RESET_TERM, which force boot0sio to send default VT-100 reset command <ESC>c before all output.
This option is not compatible with PXE and VOLUME_SERIAL options, due to space constrains. Only two of these three options could be selected together.
This option is turned off by default.
