Rajalakshmi Srinivasaraghavan	571eadb880	powerpc: Optimized SGEMM/DGEMM/CGEMM for POWER10 This patch introduces new optimized version of SGEMM, CGEMM and DGEMM using power10 Matrix-Multiply Assist (MMA) feature introduced in POWER ISA v3.1. This patch makes use of new POWER10 compute instructions for matrix multiplication operation. Tested on simulator and there are no new test failures. Cycles count reduced by 30-50% compared to POWER9 version depending on M/N/K sizes.

Fix to store results in correct order for POWER10 GEMM kernels

There is a recent compiler change in __builtin_mma_disassemble_acc() which
affects the order of storing result in POWER10. Also removing new LDFLAG
-mno-power10-stub as it is handled by linker automatically.

powerpc: Optimized SGEMM/DGEMM/CGEMM for POWER10

This patch introduces new optimized version of SGEMM, CGEMM and DGEMM
using power10 Matrix-Multiply Assist (MMA) feature introduced in
POWER ISA v3.1. This patch makes use of new POWER10 compute instructions
for matrix multiplication operation.

Tested on simulator and there are no new test failures.
Cycles count reduced by 30-50%  compared to POWER9 version depending on
M/N/K sizes.
