OpenWRT's developer guide prefers having actual patches so they an be
sent upstream more easily.
However, in this case, Adding proper fields also allows for `git am` to
properly function. Some of these patches are quite old, and lack much
traceable history.
This commit tries to rectify that, by digging in the history to find
where and how it was first added.
It is by no means perfect and also shows some patches that should have
been long gone.

Currently we fix interrupts/timers for the secondary CPU by patching
vsmp_init_secondary(). Get a little bit more generic and use the
upstream recommended way instead. Additionally avoid a check around
register_cps_smp_ops() because it does that itself.

The RTL9300 has a broken R4K MIPS timer interrupt, however, the
R4K clocksource works. We replace the RTL9300 timer with a
Clock Event Timer (CEVT), which is VSMP aware and can be instantiated
as part of brining a VSMTP cpu up instead of the R4K CEVT source.
For this we place the RTL9300 CEVT timer in arch/mips/kernel
together with other MIPS CEVT timers, initialize the SoC IRQs
from a modified smp-mt.c and instantiate each timer as part
of the MIPS time setup in arch/mips/include/asm/time.h instead
of the R4K CEVT, similarly as is done by other MIPS CEVT timers.
