Alexey Korolev 8a4c2495b1 MTD: nandsim: use less RAM 
Nandsim consumes ~2x more RAM than the density of simulated device.
It becomes critical if we need to simulate 256MB NAND and run stress tests
on it.

We investigated the reasons. nandsim allocates space for pages using kmalloc
function. The size of LP nand page is 2112 bytes.
kmalloc gets space from slab pools by chunks 2^n. So if we need to kmalloc
2112 bytes, 4096 bytes will be consumed by system.
The best way to avoid this issue would be using kmem_cache allocations. AFAIK
this mechanism specially designed to handle cases when arrays of allocations
are used.
