If we are running on RISC-V emulator/simulator with large number of HARTs where each HART is a regular thread under UNIX host then it is possible that some of the secondary HARTs don't get chance to run and sbi_hart_wake_coldboot_harts() is called before secondary HARTs call sbi_hart_wait_for_coldboot(). In this situation, some of the secondary HARTs will never come-out of coldboot wait loop. To tackle this, we introduce a global flag coldboot_done which will be protected by coldboot lock and it will be set by primary HART from sbi_hart_wake_coldboot_harts() before waking-up secondary HARTs. We also re-arrange acquire/release of coldboot lock to reduce further chances of race-condition.
