part_efi: dcache: allocate cacheline aligned buffers
Currently part_efi.c allocates buffers for the gpt_header, the legacy_mbr, and the pte (partition table entry) that may be incorrectly aligned for DMA operations. This patch uses ALLOC_CACHE_ALIGN_BUFFER for the stack allocated buffers and memalign to replace the malloc of the pte.
