efi/x86: Remove GDT setup from efi_main
The 64-bit kernel will already load a GDT in startup_64, which is the
next function to execute after return from efi_main.
Add GDT setup code to the 32-bit kernel's startup_32 as well. Doing it
in the head code has the advantage that we can avoid potentially
corrupting the GDT during copy/decompression. This also removes
dependence on having a specific GDT layout setup by the bootloader.
Both startup_32 and startup_64 now clear interrupts on entry, so we can
remove that from efi_main as well.
