Each EFI partition table entry contains a UUID. Extend U-Boot's struct
disk_partition to be able to store this information, and modify
get_partition_info_efi() to fill it in.

The implementation of uuid_string() was derived from the Linux kernel,
tag v3.6-rc4 file lib/vsprintf.c function uuid_string().

Enhance get_partition_info_efi() to range-check the partition number.
This prevents invalid partitions being accessed, and prevents access
beyond the end of the gpt_pte[] array.

Commit deb5ca80 "disk: part_efi: fix
**pgpt_pte == NULL" modified the code to pass "&gpt_head" to
is_gpt_valid() rather than the previous "gpt_head". However, gpt_head
is a pointer to the buffer, not the actual buffer, since it was allocated
using ALLOC_CACHE_ALIGN_BUFFER. This caused is_gpt_valid() to read the
disk block onto the stack rather than into the buffer, causing the
code to fail.

This change reverts that portion of the commit mentioned above.

Code was setting **pgpt_pte == NULL, which meant that the pointer
to the gpt_pte would be stored at RAM address 00000000. This 'worked'
on T20 (SDRAM starts @ 0x00000000), but hung gpt/EFI access on T30
(SDRAM starts @ 0x80000000).

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.

Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.

IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)

This driver support mflash IO mode.

Followings are brief descriptions about IO mode.

1. IO mode based on ATA protocol and uses some custom command. (read
   confirm, write confirm)
2. IO mode uses SRAM bus interface.

The ending LBA is inclusive. Hence, the partition size should be
((ending-LBA + 1) - starting-LBA) to get the proper partition size.

This is confirmed against the results from the parted tool.
(e.g. use parted /dev/sda -s unit S print) and observe the size.
