pwpiwi 7a53739728 fixing some fpga and iclass issues
* make fpga_version_info.c phony and delete it on 'make clean'
* wait for transfer to complete before returning from FpgaSendCommand()
* log correct tag times in iclass simulation
* shorten pulse from TC1 to TC0 in StartCountSspClk()
* shorten ssp_frame pulse in fpga/hi_reader.v
* some reformatting and whitespace fixes
