[U-Boot] [PATCH v7 4/7] armv8: ls2080a: Declare spin tables as reserved for efi loader

[Alexander Graf]

The efi loader code has its own memory map, so it needs to be aware where
the spin tables are located, to ensure that no code writes into those
regions.

Signed-off-by: Alexander Graf <agraf at suse.de>

v6 -> v7:

  - Don't call efi_loader functions for SPL code
