unicore32: get rid of superfluous __GFP_REPEAT 

__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations.

PGALLOC_GFP uses __GFP_REPEAT but it is only used in pte_alloc_one,
pte_alloc_one_kernel which does order-0 request.  This means that this
flag has never been actually useful here because it has always been used
only for PAGE_ALLOC_COSTLY requests.
