linux-fslc-mx6-rt: Add new recipe
This recipe is based on the now-deleted linux-imx-rt recipe, using the same set of patches. The linux-fslc-mx6 kernel is currently at upstream version 3.14.54, for which no realtime patch has been released, but patch 3.14.51-rt52 applies cleanly.

1Work around CPU stalls in the imx-sdma driver by replacing spinlocks
2with raw spinlocks. This prevents preemption during the spinlock's
3critical section, as is the case on non PREEMPT_RT kernels.
