3998c97756 HV: [v2] bugfix in 'hv_access_memory_region_update()'
- bugfix:the actual 'size' of memory region that
    to be updated is incorrect.

  - replace CONFIG_UEFI_STUB with DMAR_PARSE_ENABLED
    when update memory pages for ACPI_RECLAIM region,
    as DMAR_PARSE_ENABLED may be enabled on non-EFI
    platform.

V2 update:
    wrap roundup to 2M and rounddown to 2M inline
    functions.
