Subject: [PATCH] fix(libdmr): strip LoongArch out of Platform::Mips

LoongArch is not MIPS-based Loongson and exhibits significantly different
performance characteristics (try ~50 - 100% faster with current hardware
versus 3A4000).

There is no need to strip out functionalities in order to obtain acceptable
performance. The current 3A6000 processors can easily keep up with 10th Gen
Intel i3 processors.
