MA-18775 system will hang about 3s when boot up kernel

system will hang at line 1834 which will hold console_waiter
1833    /* Owner will clear console_waiter on hand off */
1834    while (READ_ONCE(console_waiter))
1835           cpu_relax();
1836    spin_release(&console_owner_dep_map, _THIS_IP_);

It means  console_lock_spinning_disable_and_check is not called in time.
So console_unlock may not called in time.
remove earlycon as workaround.
