ACPI / PM: Call suspend_nvs_free() earlier during resume

It turns out that some device drivers map pages from the ACPI NVS region
during resume using ioremap(), which conflicts with ioremap_cache() used
for mapping those pages by the NVS save/restore code in nvs.c.

Make the NVS pages mapped by the code in nvs.c be unmapped before device
drivers' resume routines run.
