The rtc_lock spinlock aims to serialize access to the CMOS RTC between the UEFI firmware and the kernel drivers that use it directly. However, x86 is the only arch that performs such direct accesses, and that never uses the time related UEFI runtime services. Since no other UEFI enlightened architectures have a legcay CMOS RTC anyway, we can remove the rtc_lock spinlock entirely.
