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.
For easier readability, I kept the functional changes separate from the update of the device-tree-bindings documentation.
Changes in v2: * CONFIG_EFI_PARTITION_ENTRIES_OFF is configurable via Kconfig * added clamping to ensure that the parititions are never put into the first to LBAs of a device * documented the new /config property (and moved the documentation of /config properties into a separate file per Simon's review comment)
