meta-crystalforest: Zlib QAT_MEM MM Module

The zlib software library and the Intel QuickAssist Technology both implement
the deflate algorithm as described in RFC 1951.

This software accelerates the data compression algorithm in the zlib software
library via the Intel QuickAssist Technology implemented on Intel
Communications Chipsets.

(Imported from meta-intel commit 3ee02a36e0d1126fda0c6ea6a1bef4db08b8be7a)
Changed the kernel module build patch to align with fido to make sure that
the kernel module compiles. Added KERNEL_BUILDDIR to point to kernel build.
