acpi, apei, ghes: Factor out ioremap virtual memory for IRQ and NMI context.
GHES currently maps two pages with atomic_ioremap. From now
on, NMI is architectural depended so there is no need to allocate
an NMI page for platforms without NMI support.
To make it possible to not use a second page, swap the existing
page order so that the IRQ context page is first, and the optional
NMI context page is second. Then, use HAVE_ACPI_APEI_NMI to decide
how many pages are to be allocated.
