Openocd: svf: Add ability to ignore svf_check_tdo errors
Added Openocd commandline argument to ignore_error when the
read back TDO does not match to expected value specified with
TDO after masking with what is specified in MASK. This allows
to continue to play entire SVF file ignoring errors.
Error logs clearly show the failure reason and prints
read back TDO value.
