x86/boot: Annotate data appropriately

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