Fix dotprod detection

Browse Source 
This fixes the detection of dotprod capable CPUs. Previously it looked
for the `dotprod` flag, but this does not exist
(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm64/kernel/cpuinfo.c#n50).
The correct flag that specifies the dotprod capability is the `asimddp`
flag.

fixes #4931
