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.

+Subject: [PATCH] Fix for Zlib-qat Compilation issue
+
+This patch is used to fix the compliation issue when QAT is enabled with
+Zlib.
+
+When compiling the Zlib-qat by default it takes the kernel source from the host machine .
+Since we are working on the yocto recipe implementation we need to change the path
+of the kernel source by exporting the variable (KERNEL_SOURCE_ROOT) in the main recipe.
+
