MIPS: Loongson64: Mark RS780 HPET as broken
This driver is using some dangerous hack to set MMIO address for HPET,
which might break systems with other kinds of PCH.
Also, as Loongson-3 cpufreq driver never appeared in mainline,
this driver rarely got used.
So we temporarily mark it as broken until we find a better solution.
