Some architectures require their SPL loader at a fixed address within the first 16KB of the disk. To avoid an overlap with the partition entries of the EFI partition table, the first safe offset (in bytes, from the start of the device) for the entries can be set through CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig)
When formatting a device with an EFI partition table, we may need to leave a gap between the GPT header (always in LBA 1) and the partition entries. The GPT header already contains a field to specify the on-disk location, which has so far always been set to LBA 2. With this change, a configurable offset will be translated into a LBA address indicating where to put the entries.
Now also allows an override via device-tree using a config-node (see doc/device-tree-bindings/config.txt for documentation).
Tested (exporting an internal MMC formatted with this) against Linux, MacOS X and Windows.

Applied to u-boot/master, thanks!
