On arm and unicore32i the early_alloc_aligned() and and early_alloc() are
oneliner wrappers for memblock_alloc.

Replace their usage with direct call to memblock_alloc.

Why not get rid of this wrapper like you do on unicore?

ARM has early_alloc() and late_alloc() callbacks which in the end are
passed as a parameter to alloc_init_pXd() functions. 

Removing early_alloc() would require refactoring all the page table
allocation code.
