ossl: Add support for powerpc64/powerpc64le
Summary: Add support for building ossl(4) on powerpc64* by implementing ossl_cpuid and other support functions for powerpc. The required assembly files for ppc were already present in-tree. Test Plan: The changes were tested using the in-tree tools/tools/crypto/cryptocheck.c tool on both powerpc64 and powerpc64le on a POWER9 system. Reviewed by: #powerpc, jhibbits, jhb Differential Revision: https://reviews.freebsd.org/D41837
