x86: Remove x86 specific GD flags as they are not referenced at all

Browse source 
This patch removes the x86 architecture specific GD flags
(GD_FLG_COLD_BOOT & GD_FLG_WARM_BOOT), as they are not used. Only
GD_FLG_COLD_BOOT is referenced in coreboot.c but assigned in start16.S.
But the coreboot target does not use start16.S at all and boots directly
from the 32-bit start code.
