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.
