Big.LITTLE Heterogeneous architectures, as described by ARM ,
require that the instruction set architecture of the big and little
cores be compatible. However, the Samsung Exynos 9810 is known to
have different ISAs in its core.
According to , some cores are ARMv8.2 and others are ARMv8.0.
Since LSE is for ARMv8.1 and later, it should be disabled
for this broken CPU.
