Subject: [PATCH] RT: MIPS: Loongson: make the MFGPT timer depends on !PREEMPT_RT
commit 99335526b57f9e586ddaf3c2cc102abd9eb65e73 in tip.
There is a MFGPT timer in Lemote-2F family of machines, which have low
precision and not support oneshot mode, so, only let it be un-available
in PREEMTPT_RT for we have an MIPS-builtin high-resolution timer: r4k
timer.
For we disable it for PREEMPT_RT, there is no need to convert the
related lock to raw_ one.
