Pull request for UEFI sub-system for efi-2020-04-rc4 (4)

Browse source 
This series fixes several bugs:
 
 * consider the /reserved-memory node in the device tree
 * consider memory reservations created in ft_board_setup()
 * correct output of 'efidebug memmap' on the sandbox
 * correct the definition of efi_capsule_header()
 
 Furthermore some definitions needed for future patches are added to
 header files.
