Leave out gp initialization from kernel entry on mips64

On OpenBSD/mips64, the kernel is compiled with -mno-abicalls. This
disables gp-relative addressing and essentially makes gp a spare
register in the kernel. Hence it is unnecessary to initialize gp when
entering the kernel. The _gp symbol is not needed either.
