goldfish_tty.c: Use physical addresses instead of virtual
Re-implement Goldfish TTY device to work directly with
physical addresses instead of virtual. Main idea behind
this approach is to move away from using
cpu_memory_rw_debug() -> cpu_phys_page_debug() path
for VA-PA translation, which does not guarantee that it
will return a valid mapping. Using physical addresses
is the correct way to go, ensures less overhead and
faster serial communication.
