x86/early_printk: Set __iomem address space for IO

There are following warnings on unpatched code:

arch/x86/kernel/early_printk.c:198:32: warning: incorrect type in initializer (different address spaces)
arch/x86/kernel/early_printk.c:198:32:    expected void [noderef] <asn:2>*vaddr
arch/x86/kernel/early_printk.c:198:32:    got unsigned int [usertype] *<noident>
arch/x86/kernel/early_printk.c:205:32: warning: incorrect type in initializer (different address spaces)
arch/x86/kernel/early_printk.c:205:32:    expected void [noderef] <asn:2>*vaddr
arch/x86/kernel/early_printk.c:205:32:    got unsigned int [usertype] *<noident>

Annotate it proper.
