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. Signed-off-by: Michal Simek <monstr@monstr.eu>
