ia64: Set System RAM type and descriptor
Change efi_initialize_iomem_resources() to set 'flags' and
'desc' for EFI memory types. IORESOURCE_SYSRAM, a modifier bit,
is set for System RAM as IORESOURCE_MEM is already set.
IORESOURCE_SYSTEM_RAM is defined as
(IORESOURCE_MEM|IORESOURCE_SYSRAM). I/O resource descriptor is
set for "ACPI Non-volatile Storage" and "Persistent Memory".
Also set IORESOURCE_SYSTEM_RAM for "Kernel code", "Kernel data",
and "Kernel bss".
