This patch moves the kernel modules code from EAL to a common place.
 - Separate the kernel module code from user space code.

Signed-off-by: Hemant Agrawal <hemant.agrawal@nxp.com>

Tested-by: Bruce Richardson <bruce.richardson@intel.com>

---
v6: added meson build support
v5: rearrange kernel compliation as per Bruce's suggestion
v4: update the path in MAINTAINERS
v3: move contigmem from bsdapp
v2: rename kern to kernel, add freebsd modules as well

Hi Hemant,

from testing on FreeBSD, I believe these are the changes needed to allow
compilation with meson there. Nothing too drastic - mainly fix up the
folder names, and skip the subdir into the higher-level "freebsd" folder.
