kernel-module-mcc: provide recipe adapted to a 3.18 based Toradex kernel

Browse Source 
This adds a recipe for the forked version of the MCC kernel module. The
fork includes changes to compile and run the module with the 3.18 based
kernel provided by linux-toradex_3.18.bb.

The forked version requires the functionality of the SEMA4 and MSCM
CPU2CPU interrupts exported by the kernel through some Vybrid specific
symbols:
- mscm_request_cpu2cpu_irq
- mscm_free_cpu2cpu_irq
- mscm_trigger_cpu2cpu_irq
- mvf_sema4_assign
- mvf_sema4_deassign

Currently, those symbols are provided by the Toradex Linux kernel only
(linux-toradex_3.18.bb).
