ACPI: reboot: Avoid racing after writing to ACPI RESET_REG
According to the ACPI spec, "The system must reset immediately following
the write to the ACPI RESET_REG register.", but there are cases that the
system does not follow this and results in racing with the subsequetial
reboot mechanism, which brings unexpected behavior.
Fix this by adding a 15ms delay after writing to the ACPI RESET_REG.
