x86: start annotating early ioremap pointers with __iomem
Impact: some new sparse warnings in e820.c etc, but no functional change.
As with regular ioremap, iounmap etc, annotate with __iomem.
Fixes the following sparse warnings, will produce some new ones
elsewhere in arch/x86 that will get worked out over time.
arch/x86/mm/ioremap.c:402:9: warning: cast removes address space of expression
arch/x86/mm/ioremap.c:406:10: warning: cast adds address space to expression (<asn:2>)
arch/x86/mm/ioremap.c:782:19: warning: Using plain integer as NULL pointer
