[PATCH v6 12/28] x86/boot/compressed: annotate data appropriatelly

[Jiri Slaby <jslaby@suse.cz>]

Use the new SYM_DATA, SYM_DATA_START, and SYM_DATA_END* macros for data.

Now, the data in the object file look sane:
Value   Size Type    Bind   Vis      Ndx Name
  0000    10 OBJECT  GLOBAL DEFAULT    3 efi32_boot_gdt
  000a    10 OBJECT  LOCAL  DEFAULT    3 save_gdt
  0014     8 OBJECT  LOCAL  DEFAULT    3 func_rt_ptr
  001c    48 OBJECT  GLOBAL DEFAULT    3 efi_gdt64
  004c     0 OBJECT  LOCAL  DEFAULT    3 efi_gdt64_end

  0000    48 OBJECT  LOCAL  DEFAULT    3 gdt
  0030     0 OBJECT  LOCAL  DEFAULT    3 gdt_end
  0030     8 OBJECT  LOCAL  DEFAULT    3 efi_config
  0038    49 OBJECT  GLOBAL DEFAULT    3 efi32_config
  0069    49 OBJECT  GLOBAL DEFAULT    3 efi64_config

All have correct size and type now.
