[PATCH v3 1/2] efd: fix AVX2 support

[Thomas Monjalon]

When switching to Meson build, the compilation check on CC_SUPPORT_AVX2
became obsolete, thus the case EFD_LOOKUP_AVX2 became dead.
The function efd_lookup_internal_avx2() was never called,
and its header include rte_efd_x86.h has been removed later.

EFD_LOOKUP_AVX2 is chosen at runtime after checking AVX2 availability,
so the obsolete build-time check for AVX2 can be simply removed,
and the missing include added back.

Fixes: 5b9656b157d3 ("lib: build with meson")
Fixes: 30a1de105a5f ("lib: remove unneeded header includes")
