[PATCH 3/3] x86: fix early_iounmap() sparse warnings in setup.c

[Linn Crosetto]

Replace calls to early_iounmap() with early_memunmap() for pointers
mapped with early_memremap() to eliminate the following sparse warnings:

arch/x86/kernel/setup.c:355:31: warning: incorrect type in argument 1 (different address spaces)
arch/x86/kernel/setup.c:441:31: warning: incorrect type in argument 1 (different address spaces)
arch/x86/kernel/setup.c:470:31: warning: incorrect type in argument 1 (different address spaces)
arch/x86/kernel/setup.c:491:31: warning: incorrect type in argument 1 (different address spaces)
