efi/libstub: gop: Fix EDID support in mixed-mode
The efi_edid_discovered_protocol and efi_edid_active_protocol have mixed
mode fields. So all their attributes should be accessed through
the efi_table_attr() helper.
Doing so fixes the upper 32 bits of the 64 bit gop_edid pointer getting
set to random values (followed by a crash at boot) when booting a x86_64
kernel on a machine with 32 bit UEFI like the Asus T100TA.
Fixes: 17029cdd8f9d ("efi/libstub: gop: Add support for reading EDID")
