microblaze: move the ARCH_{DMA,SLAB}_MINALIGN definitions to asm/cache.h
...
The microblaze architecture defines ARCH_DMA_MINALIGN in asm/page.h. Move
it to asm/cache.h to allow a generic ARCH_DMA_MINALIGN definition in
linux/cache.h without redefine errors/warnings.
While at it, also move ARCH_SLAB_MINALIGN to asm/cache.h for
consistency.

microblaze: Define correct L1_CACHE_SHIFT value
...
Microblaze cacheline length is configurable and current cpu
uses two cacheline length 4 and 8.
We are taking conservative maximum value to be sure that cacheline
alignment is satisfied for all cases.
Here is the calculation for cacheline lenght 8 32bit=4Byte values
which is corresponding with SHIFT 5.
