linux-toradex-fsl-rt: Added a real-time kernel recipe

A new i.MX6 real-time kernel recipe was added with a modified
PREEMPT_RT patch to accomodate the backports applied to the
Toradex kernel.

To select the kernel use a preferred provider variable in your
configuration files (e.g. local.conf):
PREFERRED_PROVIDER_virtual/kernel = "linux-toradex-fsl-rt"
