Hi all,

Both QEMU MIPS loongson3-virt and riscv virt machine are using
goldfish_rtc as sole RTC
device, it have been hardcoded in QEMU for a long while and sudden drop
in kernel would
break these machines.
RTC is essential for virt machines to keep time synchronized with host.

Given that it is the simplest RTC implementation for now, it won't give
us much maintenance

Thus I do think it shouldn't be retired as for now. If nobody comes in
I'd also willing to maintain
