rombios: remove packed attribute for pushad_regs_t

The structure already has explicitly padding.

Removing the attribute silences a clang 6 warning:

tcgbios.c:1519:34: error: taking address of packed member 'u' of class or structure 'pushad_regs_t' may result in an unaligned pointer value [-Werror,-Waddress-of-packed-member]
                                                  ®s->u.r32.edx);
                                                   ^~~~~~~~~~~~~~~
