Introduce mmc distributed lock
The locks are distributed in the kernel heaps (one lock in each cluster) and there is a global table in the kernel data segment which contains the addresses of all the locks.
The _mmc_boot_mode variable is defined in boot.c and kernel_init.c and defines which kind of lock is used.
The distributed locks are initialized inside the kernel_init() function.
