bugfix: vm halt when in reset looping
reset mc146818rtc device when RESET event happens.
Fix the problem:
1. Guest boot the second cpu, set CMOS_RESET_CODE 0x0a to protect selfboot;
2. VM being reset by others, hmp_system_reset;
3. seabios resume check the CMOS_RESET_CODE, if 0x0a, jump to the BDA
resume execution by jump via 40h:0067h;
4. Guest halt;
