[patch 78/85] arm, s390, unicore32: remove oneliner wrappers for memblock_alloc()

[akpm@xxxxxxxxxxxxxxxxxxxx]

From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: arm, s390, unicore32: remove oneliner wrappers for memblock_alloc()

arm, s390 and unicore32 use oneliner wrappers for memblock_alloc(). 
Replace their usage with direct call to memblock_alloc().
