This reverts commit 426fa8e4fe7bb914b5977cbce453a9926bf5b2e6.

The commit has caused two issues on Loongson 3A4000:

1. The timestamp in dmesg become erratic, like:

[3.736957] amdgpu 0000:04:00.0: ... ... [3.748895] [drm] Initialized amdgpu ... ... [18446744073.381141] amdgpu 0000:04:00:0: ... ... [1.613326] igb 0000:03:00.0 enp3s0: ... ...

2. More seriously, some workloads (for example, the test stdlib/test-cxa_atexit2 in the Glibc test suite) triggers an RCU stall and hang the system with a high probably (4 hangs out of 5 tests).

Revert this commit to use jiffie on Loongson MIPS systems and fix these issues for now. The root cause may need more investigation.
