arch: Set IORESOURCE_SYSTEM_RAM flag for System RAM
Set IORESOURCE_SYSTEM_RAM in flags of resource ranges with
"System RAM", "Kernel code", "Kernel data", and "Kernel bss".
Note that:
- IORESOURCE_SYSRAM (i.e. modifier bit) is set in flags when
IORESOURCE_MEM is already set. IORESOURCE_SYSTEM_RAM is defined
as (IORESOURCE_MEM|IORESOURCE_SYSRAM).
- Some archs do not set 'flags' for children nodes, such as
"Kernel code". This patch does not change 'flags' in this
case.
