giet_tsar: updating giet_tsar to use new hard_config format
Other optimizations:
- Using a memory lock instead of the hard lock for the TTY
- Each tty channel data is aligned to a cacheline (lock and buffers).
- The applications' ldscript is generated from a template which
includes the hard_config.h file.
