x86/boot: Simplify the GDTR calculation assembly code a bit
This patch calculates the GDTR's base address via a single instruction.
( EBP contains the address where it is loaded and GDTR's base address is
already set to "gdt" in compilation. It is fine to get the correct base
address by adding the delta to GDTR's base address. )
