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.
