For issue dgemm performance degradation on ARM NEOVERSEV1 with lower P*Q #4323 updated the SGEMM and DGEMM PQ param as per the configuration of NEOVERSEV1 cache size. Not keeping too big but enough to get better performance and close enough to half of the cache size.
Below is OpenBLAS/gemm.c benchmark on single core ( also seen on multicore) of graviton3 machine. Performance for SGEMM improved by ~ 2-5% and DGEMM improved by ~2-12%
@martin-frbg please help to get it review and merge.
